Package: fchart
Installation------------* Execute the setup.py script and read the help:$ python setup.py install --helpOnce confident with the options, execute:$ python setup.py install* Make sure that the fchart module library  resides in a directorythat is in your PYTHONPATH. The default settings ensure this.--OPTIONAL---* Get the Tycho2 star catalog from:http://cdsweb.u-strasbg.fr/viz-bin/ftp-index?/ftp/cats/aliases/T/TYC2* Unzip all the .dat.gz files* Concatenate the 'tyc2.dat.??' files using, e.g.$ cat tyc2.dat.?? >tyc2.dat* Execute the tyc2_to_binary.py script:$ python tyc2_to_binary <TYCHO_DIR> <TARGET_DIR>if TARGET_DIR is not specified, it will be the ..../fchart/catalogsdirectory.RUNNING-------$ fchart m45$ lsand see what happened* If there are complaints that certain python modules cannot be found,make shure that the directory containing astrocalc.py, revngc.py arein your PYTHONPATH environment variable.type$ man `echo $SHELL | sed -e"s/.*\/\(.*\)/\1/g"`if you do not know how to set environment variables.* fchart --help dumps a short manual to your screen.That's all.  You can view the output using ghostview, gv, or whateverpostscript viewer you prefer. There is also PDF output (-O pdf)Michiel------------------------------------------------------*The* manual:Usage: fchart [options] sourcename1 sourcename2 ...Output filenames are "sourcename1.eps", "sourcename2.eps", etcetera.Options:-h, --help            print help-d, --deep-sky        deepsky limiting magnitude (default: 12.5)-s, --stars           stellar limiting magnitude (default: 13.8)-p, --paper-width     width of the map in mm (default: 180.0)-f, --field-size      diameter of the field of view in degrees(default: 7.0)-m, --force-messier   select all Messier objects, regardless of thelimiting magnitude for deepsky objects-o, --output-dir      specify the output directory             (default: .)-O, --output-type     specify output fileformat. Either EPS orPDF. On posix systems this defaults toEPS. On other systems the default is PDF. EPSoutput is generally a lot compacter infilesize than (even compressed) pdf outputbecause PDF does not have a native 'circle'command (and circles we draw...). For richfields, it takes considerably more time togenerate PDF output than to generate EPSoutput, due to compression of the PDF streams.-l, --language        specify language on the maps, either 'en' or 'nl'(default: en)-a, --force-asterisms force plotting of  asterisms in map. By default, only"Messier" asterisms are plotted. All others areignored. The default setting helps cleaning upespecially Virgo cluster maps.-u, --force-pg        by default, objects in external galaxies are onlyplotted if their magnitude is known and lower thanthe limiting magnitude of deepsky objects. If thisoption is given, also objects in external galaxiesof which the magnitude is not known are plotted. Thisoption will clutter some galaxies like M 101 andNGC 4559.-x, --add-cross       add a cross in the map at a specified position. Theformat of the argument of this option is:"rah:ram:ras,+/-decd:decm:decs,label,labelposition"For example: -x"20:35:25.4,+60:07:17.7,SN,t" forthe supernova sn2004et in NGC 6946. The label positioncan be 't' for top, 'b' for bottom, 'l' for left, or'r' for right. The label and label position may beomitted.Sourcenames:Valid sourcenames are for example:- NGC891, NgC891, n891 or 891 for NGC objects- IC1396, i1396, iC1396, I1396 for IC objects- m110, M3 for Messier objectsThere is one special sourcename, which is "allmessier". When this nameis encountered, fchart dumps maps of all messier objects to the outputdirectory.------------------------------------------------------Catalogs included: saguaro astronomy club v.7.2 and revised NGC/IC projectPreferred names:MNGCICotherAll catalogs:Abell      - George Abell (planetary nebulae and galaxy clusters)ADS        - Aitken Double Star catalogAM         - Arp-Madore (globular clusters)Antalova   - (open clusters)Ap         - Apriamasvili (planetary nebulae)Arp        - Halton Arp (interacting galaxies)Bark       - Barkhatova (open clusters)B          - Barnard (dark nebulae)Basel      - (open clusters)BD         - Bonner Durchmusterung (stars)Berk       - Berkeley (open clusters)Be         - Bernes (dark nebulae)Biur       - Biurakan (open clusters)Blanco     - (open clusters)Bochum     - (open clusters)Ced        - Cederblad (bright nebulae)Cr         - Collinder (open clusters)Czernik    - (open clusters)DDO        - David Dunlap Observatory (dwarf galaxies)Do         - Dolidze (open clusters)DoDz       - Dolidze-Dzimselejsvili (open clusters)Dun        - Dunlop (globular clusters)Fein       - Feinstein (open clusters)Frolov     - (open clusters)Gum        - (bright nebulae)H          - William Herschel (globular clusters)Haffner    - (open clusters)Harvard    - (open clusters)He         - Henize (planetary nebulae)Hogg       - (open clusters)HP         - Haute Provence (globular clusters)Hu         - Humason (planetary nebulae)IC         - 1st and 2nd Index Catalogs to the NGC(All types of objects except dark nebulae)Isk        - Iskudarian (open clusters)J          - Jonckheere (planetary nebulae)K          - Kohoutek (planetary nebulae)King       - (open clusters)Kr         - Krasnogorskaja (planetary nebulae)Lac        - Lacaille (globular clusters)Loden      - (open clusters)LDN        - Lynds (dark nebulae)Lynga      - (open clusters)M          - Messier (all types of objects except dark nebula)MCG        - Morphological Catalog of GalaxiesMe         - Merrill (plantary nebulae)Mrk        - Markarian (open clusters and galaxies)Mel        - Melotte (open clusters)M1 thru M4 - Minkowski (planetary nebulae)NGC        - New General Catalog of Nebulae & Clusters of Stars.(All types of objects except dark nebulae)Pal        - Palomar (globular clusters)PC         - Peimbert and Costero (planetary nebulae)Pismis     - (open clusters)PK         - Perek & Kohoutek (planetary nebulae)RCW        - Rodgers, Campbell, & Whiteoak (bright nebulae)Roslund    - (open clusters)Ru         - Ruprecht (open clusters)Sa         - Sandqvist (dark nebulae)Sher       - (open clusters)Sh         - Sharpless (bright nebulae)SL         - Sandqvist & Lindroos (dark nebulae)SL         - Shapley & Lindsay (clusters in LMC)Steph      - Stephenson (open clusters)Stock      - (open clusters)Ter        - Terzan (globular clusters)Tombaugh   - (open clusters)Ton        - Tonantzintla (globular clusters)Tr         - Trumpler (open clusters)UA         - Catalog of selected Non-UGC galaxiesUGC        - Uppsala General Catalog (galaxies)UKS        - United Kingdom Schmidt (globular clusters)Upgren     - (open clusters)VV         - Vorontsov-Velyaminov (interacting galaxies)vdB        - van den Bergh (open clusters, bright nebulae)vdBH       - van den Bergh & Herbst (bright nebulae)vdB-Ha     - van den Bergh-Hagen (open clusters)Vy         - Vyssotsky (planetary nebulae)Waterloo   - (open clusters)Westr      - Westerlund (open clusters)Zw         - Zwicky (galaxies)
