local-format catalogs in memory between batched searches to save time and I/O.
The -i option was added to newfits
to fill the data section of a new FITS file from a binary file. The -s
option was added to imrot to split multi-extension
FITS files to fileroot_n.fits. A variety of bugs were fixed, too.
13 June 2000

1 May 2000
|scat search buffer allocation was improved
to speed searches. IRAF .imh files which keep their .pix files in a
subdirectory of the header directory are now handled correctly. All
dates in the old FITS format with three- as well as two-digit years
have 1900 added to them. TDC ASCII-format catalog files can now have
positions in fractional degrees. The hadd() subroutine now avoids
overwriting the added header line.
28 March 2000
|gethead can now extract values
from keyword=value strings in any ASCII file; keyword values can
be tested to decide whether to display the keywords from a specific
file; and embedded spaces in keyword values can be replaced with underscores.
imwcs can iterate both with and without
reducing tolerances on each iteration. IRAF .imh file header and pixel
file paths up to 256 characters, the IRAF 2.11 limit, can now be handled;
the old limit was 67 characters. A leap year bug which affected 2000-02-29
and a couple of days before was fixed. Proper motion reporting was added
to scat for Starbase output.

imcat was fixed. The year 100 in old
FITS dates is assumed to be 2000.
20 December 1999
|getdate is a new program to convert
between one date format and any other date format. -c (set constant),
-r (square root), and -g (Gaussian noise) options were added to the

getpix to print all pixels in a specified
region with a specified range of values. Strings starting with D or E,
followed by numbers are no longer assumed to be numbers. Conversion
to Julian Dates was fixed.
1 December 1999
|-a (sum), -c (count), and -m (mean) options were added to
getcol. An option was added to
imhead to output the exact FITS header,
without linefeeds. A specific editor can be specified for
edhead using the -e option as well as
through the EDITOR environment variable. A variety of bugs were
fixed throughout the package.
5 November 1999
imwcs now read Starbase files as well as
DAOPHOT-format files for star x-y input (-d).
sumpix has added options to compute means,
variances, and standard deviations of regions of an image.
getcol is a new task for gettign information
from ASCII space-delimited tables. Unix lint and Insure++ were run on
all the code and a variety of memory leak and allocation problems were
found and corrected. The catread.c library files and the subroutines it
contains were rename ctg* to avoid system subroutine name conflicts.
21 October 1999
|Changes were made in several programs and subroutines to deal with
reallocating the FITS header buffer if it got too large.
28 September 1999
|Access to the HST Guide Star Catalog by number in
scat was fixed. i2f
can now output a FITS file to standard output.

a new WCS specified on the command line. IRAF .imh files no longer
produce multiple OBJECT keywords when converted to FITS
16 September 1999
|Most of the changes were in
imwcs, and immatch
catalog access, with distance-sorted
searches now working consistently, and tab table catalog coordinate
systems being dealt with correctly. Catalog access subroutines
are all accessed through catread() and catrnum(), so new catalog formats
will be easier to add. A CD matrix initialization bug was fixed in
the fitting code.
31 August 1999
|Bugs were fixed in >scat when dealing
with coordinates following search box. A bug searching fields which
contained 0h RA was also fixed.

form name_i when a character value is too long so no information
gethead, with changes in the hgetm()
subroutine in hget.c, now can read multiline
keywords of the form name_i, name_ii, and name_iii(IRAF), concatenating
all values into one returned string when gethead name is typed.
sethead now can deal with
simultaneous files of keywords and filenames.
A fatal bug in immatch was fixed.
9 July 1999
|A slew of bugs in imwcs were fixed:
command line rotation angle setting, converting image coordinates to
reference system, command line reference pixel use, incorrect initialization
of CDELT1 when rotating an image, and correct setting of RADECSYS to FK%
or FK4, not J2000 or B1950.
The command line rotation bug was also fixed in

|Support for the ACT catalog has been added throughout the toolkit.
New programs include conpix,
to operate on all of the pixels of an image,
gettab, to extract values from tab table
data base files, and
newfits, to create dataless or blank
FITS image files. A BITPIX=0 dataless file can be used to fit a WCS using
a star lists from another image or to hold an artifical WCS.
Bugs have been fixed in the TDC binary, TDC ASCII,
and tab table (Starbase) catalog reading routines, and support for the
ACT astrometric reference catalog has
been added. Ranges of catalog (or index) numbers and files of search
centers can be read by scat and its variants
using any of the supported catalogs. Large numbers of command line
arguments are now dealt with gracefully by
2 December 1998

scat can now read the
TDC binary catalog format,
for fast searching of catalogs, including
IRAS Point Source
and local catalogs.
4 September 1998

|Add polynomial plate fit and IRAF TNX projection. Fix various bugs.
Fit CD matrix as well as CDELT/CROTA.
Add iteration and recentering to IMWCS.
18 February 1998
|Use Mark Calabretta's WCS code instead of AIPS classic WCS subroutines
for the standard FITS projections. This is a major upgrade, hence 2.0.
15 December 1998
|Rewrite IRAF code to deal with IRAF 2.11 reformatted headers. Fix a
variety of bugs. Switch to single catalog search and image-based catalog
search programs, invoked by different names for different catalogs.
12 November 1997
|Many cosmetic bugs have been fixed as more people have used the software.
RA's are now properly converted to angular distance, so areas to be searched
at high declinations are now correct.
imwcs can now fit chip rotations as well as optical axis rotations, and it can also fit the coordinates of the optical axis. Polynomial corrections to the plane tangent projection are in the works as is support for the full Calabretta set of proposed FITS WCS standard projections.
