Return stars from the
TDC binary format
catalog file for a given RA, Dec, and magnitude range. The
SAO,
PPM, and
IRAS Point Source Catalogs
are available in this format.
ctgread.c
This contains the generic catalog reading subroutines which call
the appropriate catalog-specific subroutines, defaulting to the use of a
TDC ASCII format
catalog file for a given RA, Dec, and magnitude range.
gscread.c
Return HST Guide Stars
or GSC-ACT Guide Stars
from standard CDROM format FITS table files for
a given RA, Dec, and magnitude range. FITS I/O subroutines are called.
gsc2read.c
Return GSC II Stars
from the STScI web site for a given RA, Dec, and magnitude range.
Data come over the web as tab-separated tables and are converted
to WCSTools' internal format using subroutines from tabread.c.
sdssread.c
Return Sloan Digital Sky Survey
objects from the SDSS web site for a given RA, Dec, and magnitude range.
Data come over the web as tab-separated tables and are converted
to WCSTools' internal format using subroutines from tabread.c.
tabread.c
Return stars from a
tab table format catalog file for a
given RA, Dec, and magnitude range. Based on John Roll's Starbase format.
tmcread.c
Return 2MASS Point Sources
from the set of ASCII catalog files distributed by IRSA for a given
RA, Dec, and magnitude range.
ty2read.c
Return Tycho-2 Stars
from the catalog's standard CDROM format for
a given RA, Dec, and magnitude range.
uacread.c
Return USNO
A1.0,
A2.0,
SA1.0, or
SA2.0 Catalog stars from standard
zoned files for a given RA, Dec, and magnitude range.
ubcread.c
Return USNO
B1.0 Catalog stars from standard
zoned files for a given RA, Dec, and magnitude range.
ujcread.c
Return
USNO UJ Catalog stars from its
standard CDROM format files for a given RA, Dec, and magnitude range.
catutil.c
Subroutines to figure out catalog type from its name, format catalog
numbers, decode ranges of numbers (n1-n2,n3,n4...), and convert dates and
times between various formats.
(Added in version 2.6)
