Subject: New astronomical software: ECLIPSE
Newsgroups: sci.astro.fits
Sender: owner-fitsbits at tarsier.cv.nrao.edu
Precedence: bulk

A new astronomy oriented image processing software has just been released 
by the European Southern Observatory: ECLIPSE.

Originally aimed at processing data issued from Adonis, the Adaptive 
Optics instrument in use on the ESO 3.6 telescope, ECLIPSE can be used to 
process FITS data cubes from any kind of infra-red instrument. This tool 
is written in stand-alone ANSI C, and can be included in any standard 
data processing software.

Provided functionalities are:

       FITS file format handling 

         FITS header display 
         FITS header output to text files (for edition) 
         FITS header transfer between FITS files 
         FITS header copy from text file to FITS file 
         FITS header checking and update to standard format 

       Image processing standard features 

     All these processings can be applied to all single planes in a FITS 
     data cube. 

         Image spatial filtering (linear or morphological) 
         Image warping (deformation + resampling) 
         Pixel interpolation 
         Image basic arithmetic (+ - x / pow log exp) 
         Image normalization, threshold, absolute value 
         Image FFT 
         Cross-correlation 
         Pattern image generation 
         Image statistics extraction 

       Data cube manipulation 

         Plane, cube, pattern, or quadrant extraction from a cube 
         Cube concatenation 
         Cube averaging to one image 

       Astronomical data reduction features 

         Shift and add 
         Correlated noise removal 
         Image selection 
         Weighted averaging 
         Mosaicing 
         3-colour image combination 
         Dead pixel detection/correction 
         Linear gain map creation 

All these functions are provided as a C library, a set of Unix commands 
to call them, and C-shell scripts to perform pipe-line reductions. A 
user's manual and manual pages are also provided. 

Have a look at

Hi folks,

I'm using a robotic telescope in the states and as well as being able to
receive my images in gif format, it also offers the images in fits format.

I wonder if anyone in this newsgroup knows of any software for the Amaiga
computer that can handle this format.

Thanks in advance. 

Dave.

The NetPBM Modules on the Meeting Pearls II CD can
read and write the Fits-Format. If you have access to
the Aminet look in the directory aminet/gfx/pbm.
NetPBM consists of more than 130 Shell-programs,
each beeing stand-alone and not depending on the
other programs. A GUI can be found in aminet/gfx/pbm too.
NetPBM is a collection of tools which do the following:

 1. Import - read Images in popular formats and convert
    in one of the internal PBM formats.

 2. Image processing - manipulate the image data to
    produce many effects, including contrast, scaling
    and gamma adjustment, edge detection, etc.

 3. Export - write images in popular formats for
    use with other software.

The Support-EMail is: Ingo.Wilken at informatik.uni-oldenburg.de

The FULL installation takes more than 5 MB. My Config
is only 300 KByte small and I use it to load and convert
Fits- and PCD-Images.

*Who wants to write a Fits-DataType for the Amiga?*

Greetings from the Rhine,

                             Ralf

PS: I`m an amateur-astronomer. For stargazing I use
    a 12.5 Inch Dobsonian.

Thanks for the info Ralf. I downloaded the GUI, Help Guide and the Merged
Binaries file. Everything seems to work okay (a bit slow though).

What files are you using to keep it all down to 300K. I'm sure I don't need
all of them.

Thanks again.

Dave.

Dear all fitsers...
I am sorry to post this here since I guess it may be a question
which appear every 2 weeks ( ? ).
Is there any standard for compressed fits files ?.
I am about to include two modes of compression on our images, one
with a lossless algorithm ( storage of the difference between 2 16
bits pixels on a single byte, I presume this well known algorithm
has even a name... ), and a lossy one after the one used for
the digitised sky survey ( using H transform ). I assume I am not
the only one who has to take care of more than 1 gigabytes of images
per night, and would like to know is there are standard FITS keywords
describing these compression ( COMPRESS = T ? )
We decided it was much better to perform real time processing of the
data, then compress it by a factor of 10 and store it on CD ROMs ( which
would then hold about a week of observations ) rather than to store
everything on tape which cannot be read after 3 years... and would
prefer to conform to some kind of standard if there is such a thing.
Alain

Subject: ASCII tables, practical interpretation
Newsgroups: sci.astro.fits
Sender: owner-fitsbits at tarsier.cv.nrao.edu
Precedence: bulk

Many of the existing FITS ASCII tables consist of catalogs which were
converted from non-FITS files.  The treatment of NULL values in such
files is not entirely uniform, and neither are the needs of FITS
reading programs.  It helps to have some conventions about the
interpretation of data which address both.

Here is a (probably arguable) truth table:
++++++++
Reading a value out of a FITS ASCII table

This applies when TTYPEn is one of (Iw, Dw.d, Ew.d, Fw.d).
(If TTYPEn is Aw then the field content is always "legal".)

field   || TNULLn exists and  | otherwise
content || field matches it   |
========##====================#==============
blank   ||       NULL         | NULL      (1)
--------++ - - - -  - - - - - +--------------
legal   ||       NULL         | use field (2)
--------++ - - - -  - - - - - +--------------
illegal ||       NULL         | ERROR     (3)
--------++--------------------+--------------

The cases marked () deserve a little closer inspection.

(1)
The FORTRAN parsing semantics which are specified by the FITS papers
would force the interpretation of a blank field to be numeric ZERO.
Nonetheless, in many of the converted catalogs it is clear that the
intent of the authors should have been to insert a TNULLn = ' ' card
so that the blanks would be interpreted as a NULL.  It seems unlikely
that original table authors would not insert an explicit zero for a
field whose value was zero.  This means that the default Fortran
interpretation (ZERO) is probably not the right thing to assume.

Depending on the application it may be desirable to have an option
which permits this case to be flagged as ERROR.

(2)
In the case where TTYPEn = 'Aw' and the datatype is actually
transmitting a LOGICAL value the arguments about point (1)
and (3) apply at a later stage, but this is not within the
scope of the interpretation of FITS.

(3)
Depending on the application it may be desirable to have an option
which permits this case to be flagged as NULL.
++++++++

I have used the above truth table for the ingestion of ASCII tables
into a relational database.  It may be useful for reference or
discussion.

		Sources of FITS Information 

Preface 	

This material on sources of Flexible Image Transport System (FITS)
information is posted and updated periodically by the FITS Support
Office at the NASA Goddard Space Flight Center (GSFC).  It discusses
where general FITS information, including some answers to frequently
asked questions, can be found, and provides sources for detailed
information on FITS software and documentation. 

-------

FITS Support Office

The FITS Support Office maintains a library of FITS information
accessible from http://ssdoo.gsfc.nasa.gov/astro/fits/fits_home.html or
ftp://nssdc.gsfc.nasa.gov/pub/fits/.  The material available includes

o	"Definition of FITS," a codification of FITS for the 
	NASA/Science Office of Standards and Technology (NOST),
	available in LaTeX, uncompressed PostScript, compressed 
	PostScript and (usually) ASCII text
	(The ASCII text version may not be available for a short 
	while after the announcement of a new version.)

o	"A User's Guide to FITS", published by the FITS Support Office, 
	in LaTeX, and compressed and uncompressed PostScript 

o	Revisions to version 1.0 of the "Definition of FITS" covering the
	specification of units that were incorporated 
	into version 1.1 (text)

o	A current list of the extension type (structure) names
	registered with the International Astronomical Union FITS
	Working Group (IAUFWG) (text)

o	Rules for physical blocking on various media adopted by
	the IAUFWG (text)  

In the same directory but accessible directly via 
http://ssdoo.gsfc.nasa.gov/astro/fits/basics_info.html is the FITS
Basics and Information that used to be regularly posted to
sci.astro.fits and sci.data.formats.  It continues to be revised to
reflect current FITS developments.  It contains the following material: 

o	An overview of FITS

o	A list of FITS documents  

o	A list of software packages that support FITS, including 
		FITS <--> image converters for various platforms

o	A list of on-line FITS resources

o	A description of the FITS Support Office 

The hypertext version provides links to many of the documents, 
software, and network locations listed.  The text version provides 
information on how to obtain much of this material.

There is also a hypertext version of the List of Registered  Extensions. 

Links from the Web page and subdirectories of the ftp directory contain
	
o	Software developed by the FITS Support Office.  

o	Error test files: primary HDUs useful for testing the ability
	of software designed to read FITS files to cope with files that 
	have errors or are non-standard.  These files should be 
	downloaded in binary form.

Printed copies of the material in the FITS directory can be obtained
from the Coordinated Request and User Support Office (CRUSO):

National Radio Astronomy Observatory (NRAO)

A FITS Archive can be found at URL http://fits.cv.nrao.edu/ or 
at ftp://fits.cv.nrao.edu/fits, located at NRAO.  This machine supports a
WAIS server named nrao-fits which has an index of all of the
FITS-related text files in the archive; the file nrao-fits.src is
available at think.com and at
ftp://fits.cv.nrao.edu/fits/wais-sources/nrao-fits.src.  

Some of the more noteworthy materials in this archive are 

o	Drafts of proposed additions to the FITS standard and other 
	drafts that may in the future be formally proposed

o	Text of any detailed proposals currently being discussed by 
	the FITS committees

o	A collection of documents on World Coordinate Systems, 
	including the current draft proposal

o	Conventions specific to particular projects or disciplines

o 	Software for various environments and Usenet postings about
	code 

o	Sample data and special test files designed to measure the
        ability of a FITS reader to handle a wide variety of FITS files

o	Archives of traffic on FITS-related newsgroups and exploders

A separate NRAO site, http://www.cv.nrao.edu/~bcotton/fitsview.html,
provides information on the FITSview family of software packages for
display of FITS images on Microsoft Windows 3.1 and Windows 95, Apple
Macintosh, and Unix/X-Windows, with links to the software. It also links to
a number of sources of astronomical FITS images.

HEASARC

The NASA/Goddard High Energy Astrophysics Science Archive Research
Center (HEASARC) Web server at 
http://heasarc.gsfc.nasa.gov/docs/heasarc/fits.html and the anonymous
ftp access through ftp://heasarc.gsfc.nasa.gov/fits_info/ provide FITS
material.  HEASARC has developed the FITSIO package of software routines
for easily reading and writing FITS files, with FORTRAN and C versions
available, portable to a wide variety of machines.  There is also the
FTOOLS collection of software tools and the VERIFITS FITS conformance
verifier. HEASARC software is available directly through 
http://heasarc.gsfc.nasa.gov/docs/heasarc/tech_res_software.html or
ftp://heasarc.gsfc.nasa.gov/fits_info/software/ . 

The HEASARC server also provides information from the HEASARC FITS
Working Group, (HFWG) the internal legislative body on FITS-related
matters within the Office of Guest Investigator Programs (OGIP) at
NASA/GSFC, at 
http://heasarc.gsfc.nasa.gov/docs/heasarc/ofwg/ofwg_intro.html or at
ftp://heasarc.gsfc.nasa.gov/fits_info/ in the directories ofwg_minutes
and ofwg_recomm.  The HFWG has developed a number of FITS conventions
that are more specific than the requirements of the FITS standards.
Proposed conventions are publicized to the FITS community as a whole,
with the goal of collaborative development of a set of conventions
that will be accepted throughout the community as well as within
OGIP/HEASARC.

Subject: ANNOUNCE: perlDL v1.00 - the 'perl Data Language'
Newsgroups: adass.general,sci.astro.fits,comp.lang.idl-pvwave,comp.soft-sys.matlab,sci.astro,sci.image.processing
Sender: owner-fitsbits at tarsier.cv.nrao.edu
Precedence: bulk

    `perlDL' ("perl Data Language") gives standard perl the ability
    to COMPACTLY store and SPEEDILY manipulate the large N-
    dimensional data arrays which are the bread and butter of
    scientific computing.

    The idea is to turn perl in to a, free, array-oriented,
    numerical language in the same sense as commerical packages like
    IDL and MatLab. One can write simple perl expressions to
    manipulate entire numerical arrays all at once.

    For example with `perlDL' the perl variable `$a' can hold a
    1024x1024 floating point image, it only takes 4Mb of memory to
    store it and expressions like `$a=sqrt($a)+2' would manipulate
    the whole image in a few seconds.

    A simple interactive shell ("`perldl'") is provided for command
    line use together with a module ("`PDL'") for use in perl
    scripts.

    v1.00 is the first official alpha release. It provides the
    fundumental numerical processing facilities and a limited set of
    standard functions. Graphics are supported via the perl PGPLOT
    module and image display via the external programs
    saoimage/ximtool. The goal is to allow perlDL to interact with a
    variety of external graphics systems. I/O is currently supported
    via the FITS standard, though given the simple design it ought
    to be possible to create perl code to read many common formats.

    There are of course many things missing from this first release
    but it is hoped that perlDL will grow through efforts of
    interested users. It has a modular design to encourage this.
