Meetings/2010-11-08

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

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.

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
