The SRDP Pilot Operations intend to utilize CASA 5.4.1-32 with a custom pipeline that includes developments after the 5.4.0-69 release. These changes have broken ephemeris cube imaging in the pipeline and this imaging mode cannot be supported with the current setup.

Justification

The Pilot operations period is going to be a trial period for a limited subset of users. Ephemeris observations constitute a small fraction of the observations performed with ALMA and is not expected to substantially limit community participation. Ephemeris imaging will become available again in full Wave 1 operations because the Wave 1 will be using CASA 5.6, which will have the ephemeris imaging fixed.


Risks

Document incurred risk by one of the following options:

  1. No additional risk is incurred by this decision.

Impact

PIs desiring to re-image their ephemeris sources, planetary objects, etc., will not be able to do this in the Pilot.

Communication

This will be documented as a known issue for the pilot.
