What Cycle 9 proposal issues and clarifications should I be aware of before submitting my proposal?

Authors list

This Knowledgebase article is a repository for information relevant to submission of Cycle 9 proposals. These items may affect how users write their proposals or set up their observations in the OT. The content may evolve rapidly as the 21 April 2022 proposal deadline approaches. Items added to this list after its initial deployment will include the date they were added. We encourage all PIs to check back here regularly prior to proposal submission.

Observing Tool Known Issues - Please check this page for updates on OT known issues

C9_001For single continuum proposals where the source velocity is much larger than 0, the “Achieved RMS” in the Techincal Justification (second line) is miscalculated. The OT may also file validation errors warning that one (or more) spw has low transmission. Setting the source velocity to 0 – which should not affect a single-continuum proposal – can temporarily solve this issue.

Updated Technical Handbook - The following paragraph was removed from the Cycle 9 Technical Handbook:  ‘The MD1 mode is considered to be a “quiet Sun” mode (coronal holes, the solar limb, quiescent filaments, prominences, quiet areas outside of active regions) whereas the MD2 mode is rec- ommended for the “active Sun” (active regions, active filaments, science objectives that require accurate photometry).' Removing this helps avoid confusion from PIs when proposing observing the Sun in bands 3, 5, and 6, for which MD mode should always be the default.

No calibrator for Configurations C-8, C-9, C-10 in bands 7,8,9, or 10 - In case you receive the specific validation error “Band-to-band observing is required, but no calibrator appears to be available” and cannot submit your proposal, please contact the Proposal Submission Emergency Department on the ALMA Helpdesk as soon as possible before the Cycle 9 proposal submission deadline of 15:00 UT on Thursday, 21 April 2022 and attach your complete .aot file to the ticket.
