ska3-flight 2026.6

This PR includes:

• kadi
  • change the filtering in commands.observations.get_observations to use the observation's manvr_startand obs_stop (as opposed to obs_start and obs_stop).
  • fix an issue when getting star IDs from backstop, and in commands.observations.get_starcats.
  • Add scheduled obsid to commands, states, observations.
  • Require scenario="flight" if no internet.
  • Support HRC 15V On from SCS-85 activation.
• parse_cm: Add a new convenience function (paths.load_url_from_load_name) to get the URL for a load directory on either icxc or OCCweb based on the load name.
• chandra_aca:
  • improve ACA pixel row,col <=> angle yag,zag transformations to properly account for CCD temperature.
  • in read_manvr_mon_images: add support for new quadrant zero offsets, and for filtering based on planning constraints.

Interface Impacts:

Requires scenario="flight" if there is no internet.

This might require changes in downstream code, e.g. mica.starcheck.get_starcheck_catalog ends up calling get_observations, so now that would fail without internet. Kadi scenario can be set globally via the environment variable KADI_SCENARIO="flight" (either programatically or in a shell).

New data file
There are new kadi archive files $SKA/data/kadi/cmds3.{h5,pkl} that need to be synced.

If the files are not present, kadi falls back to use the previous version, which is fine unless one intends to use the scheduled OBSID.

Other changes in kadi

• Date-based queries that start or end within a maneuver may return additional observations relative to the previous version.
• Adds new type=LOAD_EVENT tlmsid=OBSID commands.
• Adds a new column obsid_sched to the output of get_observations().
• Adds a new state key obsid_sched to query the scheduled ObsID.
• Adds a new conf.matching_block_size configuration variable for testing.
• Adds a new environment variable KADI_CMDS_VERSION to explicitly specify the cmds archive version.
• In the function get_load_cmds_from_occweb_or_local, the archive kwarg is renamed to in_work for clarity. This function is private in practice.

Testing:

• HEAD.
• GRETA.
• OSX.

The latest release candidates will be installed in /proj/sot/ska3/test on HEAD, and all release candidates will be available for testing from the usual channels:

conda create -n ska3-flight-2026.6rc3 --override-channels \
  -c https://icxc.cfa.harvard.edu/aspect/ska3-conda/flight \
  -c https://icxc.cfa.harvard.edu/aspect/ska3-conda/test \
  ska3-flight==2026.6rc3

If this release includes an update to ska3-perl, the install process for Aspect will include that. Note: ska3-perl is generally not needed for non-Aspect users.

conda create -n ska3-flight-2026.6rc3 --override-channels \
  -c https://icxc.cfa.harvard.edu/aspect/ska3-conda/flight \
  -c https://icxc.cfa.harvard.edu/aspect/ska3-conda/test \
  ska3-flight==2026.6rc3 ska3-perl

Review

All operations critical or impacting PR's are independently and carefully reviewed. For other PR's the level of detail for review is calibrated to operations criticality. Some PR's that are confined to aspect-team-specific processing may have little to no independent review.

Deployment

ska3-flight 2026.6 will be promoted to flight conda channel and installed on HEAD and GRETA Linux upon approval of FSDS Jira ticket.
