2022.5

ska3-matlab

This PR brings ska3-matlab in sync with ska3-flight 2022.4. There are many changes. For details, see PR #899.

Release 2022.6

ska3-flight

This release includes:

• acis_thermal_check changes approved in FSDS-36.
• Changes in sparkles and proseco with a modified guide-count calculation for dynamic background.
• Various fixes for RedHat 8.

The full set of code has also been fully tested on Redhat 8 and at this time we would also like to request approval to use the ska3-flight environment on RHEL8 systems for operational use as those systems become available.

Interface Impacts:

None

Release 2022.4

This release includes:

• An update to the kadi Chandra Commands Archive V2 to include the star catalog command times (useful as a star catalog reference time). Work on this update also resulted in a new system of caching for star catalog data.
• An update to xija to support earthshine for future ACIS FP models.
• An update to parse_cm to support writing "backstop" lines to a file-like object. This small change will be an interface help for ORViewer integration.
• Minor bugfixes and doc and testing improvements.

Interface Impacts:

• The update to kadi commands does change the star catalog command date to be the new "reference" date for star catalogs. The commands archive files (cmds2.h5, cmds2.pkl) will be updated as part of promotion and will be sync'd by users following the usual sync process.

Release 2022.3

This release includes:

• ACIS load review tools
  • https://occ-cfa.cfa.harvard.edu/browse/FSDS-18
  • https://occ-cfa.cfa.harvard.edu/browse/FSDS-19
  • https://occ-cfa.cfa.harvard.edu/browse/FSDS-24
• cxotime:
  • Add new functions date2secs and secs2date for fast conversions even for scalar values
• kadi:
  • Add support for commands archive v2 (beta release). This was previously discussed, with additional details to be briefed at a DAWG session.
• maude:
  • Add support for P016
  • Add support for binary blob queries
  • Add support for allpoints, hr (high rate), nearest, icalc, ircts params
• parse_cm:
  • Add a module that translates a DOT or FOT request to backstop commands
• cheta (aka Ska.engarchive):
  • Fix bug pickling MSIDset
  • Allow CALC_ as an alias for DP_ for better interoperability with MAUDE (e.g. querying CALC_PITCH_FSS works for both CXC and MAUDE backends.
• Ska.Sun:
  • Add function to compute off-nominal roll range for a given pitch (or pitches) using a high-resolution sampled version of the roll table.

Interface Impacts:

No API breaking interface impacts are expected. Known interface changes are:

• kadi:
  • For the default v1 commands archive, the output of get_cmds now includes a new time column corresponding to the date in CXC seconds.
• sparkles:
  • Non-public function sparkles.roll_optimize.allowed_rolldev has been removed.
  • Plot of star catalog for roll options now includes the star mag for potential candidate stars.
• xija_gui_fit:
  • Numerous changes/improvements to the GUI interface including new functionality (see PR 116).

Release 2022.2

This release includes an update of ska3-flight, ska3-core and ska3-perl meta-packages. Most of the changes to ska3-flight packages were needed to comply with small changes in the interface of ska3-core packages. The following are the ska3-flight changes that are not related to core package changes:

• proseco, sparkles and starcheck now include checks for overlapping guide star tracks.

Release 2022.1

ska3-flight 2022.1

This PR includes ACIS OPS improvements.

• acis_thermal_check: 4.0.0
  • Use limits from the JSON file, refactor prediction plots
• acispy: 2.3.0
  • Use thermal limits from JSON files, support ACIS FP in SimulateECSRun, new "attitude" argument
• backstop_history: 1.5.1
  • Process a full continuity (science + vehicle commands) load as vehicle only if commanded

Interface Impacts:

No impacts.

Release 2021.15

ska3-flight 2021.15

This PR:

• Update the ska3-flight versions of the ACIS tools related to FSDS-6
• Update starcheck load review tool to:
  • Round the P2 and guide count metrics for checking to 1 decimal place
  • Add more explicit guide count checking in the per-obsid checks (was done on the full schedule "summary")
  • Print the fractional guide counts in the per-obsid reports (was just in the schedule "summary")
• Small additional package updates

Interface Impacts:

The acis_thermal_check interface impacts have already been briefed in FSDS-6

Release 2021.10

added fot-matlab

Release 2021.14

ska3-flight 2021.14

This PR includes:

• Update to starcheck load review tool to change the bright star limit to 5.2 mag.
  • The starcheck update includes an update to the ACA load review checklist consistent with the change in the bright limit for guide and acq stars. This was approved by SSAWG.
• Changes in proseco, chandra_aca, and sparkles in relation to the 5.2 mag bright star limit.
• Changes in kadi to handle the LETG move duration.

Interface Impacts:

• kadi: add a new intermediate state to the grating states to indicate the movement time between INSR and RETR. This behavior can be disabled using kadi.command.states.disable_grating_move_duration

More info

Release 2021.13

This release includes:

• acisops/acisfp_check changes to to check for -109 C violations on ACIS-S observations with the HETG or S3-only observations with < 300 expected total counts in the observing sequence.
• Mica changes to fix a bug in the web display of guide star statistics

Interface Impacts:

None
