STSDAS Version 3.7 Release Notes

  15 June 2007

This release of STSDAS contains changes to  ACS, AXE, CALSTIS, CALWP2, MultiDrizzle, PyDrizzle, SYNPHOT, and MSTOOLS as well as minor changes to CVOS and HSTIO.

One new task has been added; namely,

The specific changes are detailed in
the following sections.

Platform Support

Binaries for this release were built on Red Hat Enterprise Linux 3, Solaris 5.8, and Mac OS X 10.4 (PPC and Intel architecture).
Binaries for macintel were built and require iraf 2.13.beta from
http://iraf.net.

HST_CALIB

CALACS 4.6.3

CALACS was updated to Version 4.6.3 (14-Dec-2006). 

Bugs fixed in this version include:

AXE

AXE was updated to version 1.6. See the official aXe site for details related to this update.

NICMOS

    SAAclean:

    rnlincor:

STIS

This release contains CALSTIS Version 2.24 (23-May-2007) and represents the calibration to be used for the final reprocessing of all STIS data taken prior to SM4. 

The following bugs were corrected:

The code has seen a number of small, additional improvements related to maintainability but otherwise not affecting the algorithms or accuracy. A help file for MKTRACE was added.

WFPC2

CALWP2 has been updated to Version 2.3.0 (May 24, 2007) in this release.  This new version applies the correction to WF4 data affected by the low-bias readout problems.  This support includes:
This new calibration step corrects WF4 data for low bias levels, and flags all the pixels in the WF4 DQ array with a value of 2048 when the original (uncorrected) bias levels fall below the threshhold speecified in the reference file's WF4TBDQ keyword. 

This version also corrected a logic problem in computing each chip's statistics by explicitly keeping track of NGOODPIX for each chip and using it for computing the statistics for each chip.

Synphot

ANALYSIS

Drizzle

The help file for the drizzle task was modified to explain better the pixel values being set in the context image.

PyDrizzle 6.0

The following changes were made:

MultiDrizzle 3.0

Several bugs were fixed, including:

New support for using MultiDrizzle with WFPC2 data can also be found online at http://www.stsci.edu/hst/wfpc2/analysis/drizzle.html .

TOOLBOX

IMGTOOLS/MSTOOLS

PYTHON

A new shell command line task, print_asn, was added to print out the contents of a table to standard out without having to explicitly load IRAF, PyRAF or Python.

Libraries

CVOS

The C interface function c_tbciga was added to the cvos interface (XTABLES.def).  For a table column containing array elements, this function gets the dimension of the array and the length of each axis; this is only relevant if the array dimension is greater than one.  This is called by calstis and calnica, and it makes more sense to include the function in the C interface rather than defining interface functions in calstis and calnica.

HSTIO

The function putSingleNicmosGroupSect (and supporting routines) were added to HSTIO.

ZZSETENV.DEF
