• what's missing
• what could be improved
• what's the process for contributing

ready to release?

Minutes

Miriad manual

• questions from users?
  not that many, it seems
• the most common questions seem to relate to things that have been taken out in the ​new edition of the AT User's Guide
• people familiar with miriad know where to look for answers
• Ray Norris' ​ATUG wiki entry (login required) has glaring problems. It's far from a cookbook, more of a set of reminder notes for blackbelt users.
• Jamie has been rewriting main manual (mostly making notes-to-self) as he goes through various data reductions. This is all in a private copy of his, none of it has been checked in yet.

ATUG manual

• don't need to put much miriad material in here, point people to the cookbook.
• advise reading miriad manual before observations

Changes to miriad

• divide+conquer:
  • Emonts found it made no difference for his use-case (spectral line absorption)
  • are there any situations it is really needed?
• bandpass calibration procedure - does it need to change?
  • the need is probably frequency-dependent.
  • at 5GHz it seems there is no need for repeat bandpass measurements
  • at 8GHz, perhaps this is needed
  • higher than this we have no information
  • Emonts reported an improved rms from 1% to 0.1%, for the case of spectral line at phase centre, 5GHz.
• polarimetry
  • possible issue at 7mm, Q & U signs flipped? (ticket:103)
