The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.

RELEASE NOTES FOR HEASOFT 6.30.1
April 11, 2022
********************************************************************************
The HEASoft 6.30.1 release is driven by updates needed for IXPE
data analysis, but also includes updates to the Swift/UVOT software.
Patches are available for users who wish to update their existing
6.30 installation to 6.30.1. Please see our download page for more
information:

HEAGEN
********************************************************************************
- barycorr: Fixed orbit file column numbering issue that causes
the correction for IXPE to be in error by a random amount of
about 1 msec.

- extractor:
Added new parameter 'stokes' which can be used to select between
different weighting schemes when extracting spectrapolarimetric data.
If stokes=NONE then do not extract Stokes parameter products, if NEFF
or SIMPLE then use the weighting column defined by polwcol, and if
UNWEIGHTED then do not use the weighting column. In this last case
the I Stokes parameter product is the same as that if NONE had been
chosen. NEFF is the Baldini et al. 2203.06385 weighting scheme
and SIMPLE is that from Kislat et al. 1409.6214.
The value of this parameter is written to the keyword STOKESWT
in output files.

XSELECT
********************************************************************************
- Added new 'stokes' parameter to be used with the bin/extract
command to pass down to the extractor 'stokes' parameter.
********************************************************************************
IXPE
********************************************************************************
- IXPE tools v2.9:
* Updated to support remote CALDB access
* ixpeweights: Updated W_MOM calculation
* ixpedet2j2000.py:
a. No longer requires header keyword "FILE_LVL" to have the value of "1".
b. Now accepts multiple attitude files.
i. Requires all input attitude files to have the same values
for "RA_OBJ" and "DEC_OBJ" keywords.
c. Now calculates and outputs "Q" and "U" columns.
i. Now requires the input to contain "DETQ" and "DETU" columns.
ii. Now requires the input to contain "ABSX" and "ABSY" columns.
* ixpepolarization.py:
a. Corrected a sign error in the display of the polarization vector.
b. Added print output of the Q, U, polarization magnitude and angle
for each region.
c. Added similar output to region file for each region.
d. Changed the scaling key line size and value to a simpler value.

UVOT:
- uvotlc: (v0.4) Simplified expfile/qualfile=NONE use, and fixed
sexagesimal RA/Dec.
- uvotsource: (v4.4) Changed output for bad SSS when forcephot/skipbad
are used. Report quality+photometry flags to console.
