      TMC is compliant with ADR-95 and ADR-76. The TMC versions supporting the functionality are released.


      Added on 30 Aug 2024

      The TMC behaviour w.r.t. handling the dish static pointing model correction key is documented at: https://confluence.skatelescope.org/display/SE/Design+Diagram+of+Dish+Leaf+Node+to+use+correction+key+from+Configure+JSON+to+MAINTAIN%2C+APPLY+or+RESET+offsets+on+Dish+Manager (TBD: Move to Solution intent)
      The integration testing with Dish is not completely verified due to failures in pipeline. The team could not investigate the issues in PI 23. So the relevant story (M-521) is carried forward to PI 24.

    Description

      Ticket created to develop Feature around Dish Pointing around (ADR-95), also added work related to ADR-76.

      Most of the ADR-95 related functionality agreed to be implemented in PI21, was implemented in PI21. The only remaining change is to pass the ScanID via the Scan command. See ADR-95 page in Confluence:
      https://confluence.skatelescope.org/display/SWSI/ADR-95+DISH+Pointing

      Details for the changes to be introduced by ADR-76 are outlined on the Confluence page, but will be finalized in the week beginning on March 11. The estimates and plans should be based on the currently listed content of the ADR-76 page:
      https://confluence.skatelescope.org/display/SWSI/ADR-76+SDP+to+TMC+real-time+pointing+calibration+interface

      In general what is expected from TMC for ADR-76 is:

      1. Finalise and integrate interfaces with SDP for SDP reading of intended & actual pointing (offsets)
      2. TMC when directed by the "configure" command (see below) to wait for and retrieve calibration results from SDP and apply them to the DISH LMC
      3. Be able to parse the optional extra directives in the configure JSON sent by OSO (or otherwise loaded) that determine control over applying the calibration results from SDP:
        1. If no directive present do nothing;
        2. If the directive is to "apply" the calibration results then apply them as in (2) above;
        3. If the directive is to "reset" then instruct DISH. LMC to reset the static pointing model to its default. Note: In the first meeting discussing SS-120 (https://confluence.skatelescope.org/display/SE/2024-03-11+SS-120+AA0.5+Mid+interferometric+pointing+calibration) it was decided that "reset to default" can be taken to mean set the offset values back to 0.0, 0.0.
