Review the state of the documentation

== Agenda ==
 Miriad manual::

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

 ATUG manual::
  should we be contributing?

 PGFLAG::
  ready to release?

 Miriad manual::

 * questions from users?[[BR]]
   not that many, it seems
 * the most common questions seem to relate to things that have been taken ''out'' in the [http://www.narrabri.atnf.csiro.au/observing/users_guide/html/atug.html new edition of the AT User's Guide]
 * people familiar with miriad know where to look for answers
 * Ray Norris' [http://atug.wikidot.com/observerscheatsheet 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)
