This meeting is to discuss the large amount of development that has happened since our last meeting.

== Agenda ==
 Task development::
  Progress on eg. system temperature recalculation, WCS compliance, convenience tasks
 Recent experiences::
  Experiences with CABB reduction re: polarisation, wideband etc. and suggestions for improvements.
 Future of Miriad::
  There has been talk of a move towards CASA for certain reduction processes. We will discuss what role Miriad will/might have in the future.
 AOB::
  Anything else of note.

== Minutes ==
 * CABB systemps can be affected by RFI and/or problem channels, can't currently fix this problem
 * systemps most important when imaging
 * ATLOD can now revert to raw counts instead of online-calculated tsys, and can then recalculate after flux calibration with attsys before imaging
 * recalculation of XY phases on reference antenna is still troublesome
 * perhaps get online calculations to be more robust to interference to mitigate this problem
 * pgflag bug reports have been acted upon and fixed
 * mirflag binary and doc files can just be "dropped in" to the correct places in Miriad tree and will hence be distributed in standard distribution
 * would be useful if mirflag can work with phases, Emil thinks this is possible
 * polarisation with CABB: 
   * imrm can't work with cubes, would be handy if it could work
   * Dave finds that at 6cm over 2 GHz, the leakages change across the band, but impact of this is uncertain
 * it may be desirable for gp tasks to be transferred to mf tasks, but how much effort should be invested in this?
 * working panel will deliberate on questions re: Miriad's future
   * write a discussion paper for the next ATUC meeting
   * astro group will be consulted after 23rd November
 * Miriad is becoming a CABB calibration engine, and less useful for wideband imaging
 * CASA has plenty of issues still, needs testing and debugging
 * ASKAPsoft may also be useful, but needs to be accessible
