DESCRIPTION
gax is a UNIX command line program used to search and display
astronomical galaxy information with user control of search criteria
and display format.
OPTIONS
There are three kinds of options, 1) query, 2) display, and 3) file.
The query options specify the constraints on selecting items from the
database. The display option controls the report output format. The
file options specify canned file input, optional database output file,
and the database input file. The details of each option is given
below. Note that whenever a Min,Max pair is allowed, either of the
limits may be omitted, however, if the Max is specified then the
separating comma is mandatory for obvious reasons.
-rMin,Max
Specify the minimum and/or maximum right ascension using the
format 'hhmmss'.
-dMin,Max
Specify the minimum and/or maximum declination using the format
'+ddmmss' or '-ddmmss'.
-xMin,Max
Specify the minimum and/or maximum major axis size in minutes of
arc using the format 'nnn.n'.
-yMin,Max
Specify the minimum and/or maximum minor axis size in minutes of
arc using the format 'nnn.n'.
-vMin,Max
Specify the minimum and/or maximum visual magnitude using the
format 'nn.n'.
-pMin,Max
Specify the minimum and/or maximum photographic magnitude using
the format 'nn.n'.
-aMin,Max

GAX(1) Version 1.0 GAX(1)
Galaxy Galaxy

Specify the minimum and/or maximum absolute magnitude using the
format 'nn.n'.
-sMin,Max
Specify the minimum and/or maximum surface brightness using the
format 'nn.n'.
-zMin,Max
Specify the minimum and/or maximum recession velocity using the
format 'nnnnn'.
-mMax
Specify the maximum distance from the RA/Dec point in minutes of
arc using the format 'nn'.
-c[!]Con
Specify the constellation to be searched using the 3 character
constellation abbreviation. Multiple -c options are allowed up
to a maximum of 36. If ! is given, the specified constellation
will not be searched. Additional online help is available for
this option using '-hc'
-ONam
Specify the name of a specific object using its catalog
designation. Multiple -O options are allowed up to a maximum of
10. You may have to use quotation marks to obtain the desired
results.
-uMap
Specify the Uranometria 2000 map number to be searched using the
format 'nnn'.
-RMin,Max
Specify the minimum and/or maximum rise time for an object using
the format 'hhmmss'. [not yet implemented]
-TMin,Max
Specify the minimum and/or maximum transit time for an object
using the format 'hhmmss'.
-SMin,Max
Specify the minimum and/or maximum set time for an object using
the format 'hhmmss'. [not yet implemented]
-C[!]cat
Specify the catalog to be searched using the format 'a'. If ! is
given, objects in the specified catalogs will be ignored.
Additional online help is available for this option using '-hC'.
The currently supported catalogs are:

sequence of characters, each character representing one column of
information in the report. A particular character can appear
more than once in the sequence. The allowable option characters
and their meaning is as follows.
