Aperture Photometry Tool, v. 2.8.1, Available Now!
Fixed a sign-error bug when converting sexagesimal values that lie in the (-1, 0) range into decimal values. Thanks to Paul Leyland for reporting this problem.
Aperture Photometry Tool, v. 2.8.0, Available Now!
Added logic to function processHeaderCard in the ReadFitsFile class, in order to fix a bug that prevents loading an image from the multi-extension HST-WFPC file w0ji2201t_c0f.fits. Thanks to Richard Nowell (Bristol U.K.) for reporting this issue.
Aperture Photometry Tool, v. 2.7.9, Available Now!
Added logic to better detect HDUs containing image data in FITS files. Thanks to Paul Leyland for reporting this issue.
Aperture Photometry Tool, v. 2.7.8, Available Now!
There is a bug fix and enhancements in this release.
Bug fix: Forgot to divide output attribute ApertureNumRejected by the square of the calculational step size. Recast ApertureNumRejected from integer to double, in order to track fractional pixels.
Interface-change warning: There is a new column included in the output photometry-table file, called Flags, which is an integer that contains bit-wise binary flags for various conditions that affect the results.
lowerSrcDataLimit and upperSrcDataLimit in APT.pref).
with blanks or NaNs (not a number).
in which case, these are not included here).
Thanks to Paul Leyland for suggestions that lead to this improvement.
Aperture Photometry Tool, v. 2.7.7, Available Now!
Bug fix: Modified the WCS class to apply the PC matrix in fixing a CDELT1 sign error, which is needed for Pan-STARRS images. Thanks to Richard Nowell (Bristol U.K.) for pointing out this problem.
Aperture Photometry Tool, v. 2.7.6, Available Now!
There is an enhancement in this release.
Modified APT to check whether the to-be-loaded FITS image is compressed (regardless of filename extension). The allows the software to load Pan-STARRS images, which are compressed, but do not have the .fz filename extension. Thanks to Rick Nowell for raising this issue.
Aperture Photometry Tool, v. 2.7.4, Available Now!
There are enhancements in this release.
Forgot to increase -Xmx1024m to -Xmx2048m in the Info.plist file used for the double-click Mac application, which is normally installed in the /Applications folder (see related upgrade in the revision history for the previous version of APT below).
Increased the default maximum image size from 5Kx5K pixels to 10Kx10K pixels. It takes a minute or so to load an image this large, so be patient!
Modified the code that loads a FITS image to allow FIT and FTS (all letter-case permeatations) as FITS-filename extensions, in addition to FITS and FZ. Thanks to Jim DeYoung for this refinement.
Aperture Photometry Tool, v. 2.7.3, Available Now!
There are enhancements and bug fixes in this release.
Modified the ReadFitsFile class to more generally handle the parsing of multi-extension FITS files that include admixtures of IMAGE and TABLE header-data units (HDUs). Modified the HDU class to add XTENSION and ZTENSION as attributes. Added error checking for the case where a FITS file has no image HDUs.
Increased the default Java heap-space size allocated for APT start up from 1024 to 2048 megabytes, so that APT can load images as large as 10Kx10K pixels.
Completely overhauled the Pick/Zap Tool, in order to dramatically improved its responsiveness. Changed the default pick color from blue to cyan to differentiate it from the default blank color.
Sorted out a bug that prevented the photometry-file table header from being written when individual photometry records are saved. Thanks to Roc Cutri for apprising me of this problem.
Aperture Photometry Tool, v. 2.7.2, Available Now!
Added “Peak pixel (X, Y, value)” to the display of quantities in the “APERTURE MEASUREMENTS” box on the main GUI panel. Thanks to Jim DeYoung for this suggestion.
Modified the ReadFitsFile class to more generally handle the parsing of multi-extension FITS files.
