| Time | Item | Who | Notes |
|---|
| 5 min | Pawsey and pipelines | Aidan | - 0.24.4 of askapsoft/askappipeline now available and default on Galaxy
- Calibration table null entry fix
- Stokes V MFS image creation (without cubes)
|
| 15 min | EMU pilot survey feedback and processing | Andrew | - Observations for EMU pilot complete, see table EMU
- Processing of first block complete, CASDA upload failed due to island catalogue errors
- James will exclude the island catalogue and re-run the upload today
- Uploaded data will be visible to EMU team with unreleased status
- Processing of remaining blocks will proceed once EMU confirm that all is well
- Initial feedback from Josh is positive
- Still not hitting the CLEAN RMS threshold, ending on minor cycle iteration limit instead
- Looks like deeper CLEANing is possible without diverging
- Smallest scale is smaller than the beam, might not be used
|
| 15 min | WALLABY Eridanus processing and feedback | Karen | - Full-field half-band processing complete, but several beams have zebra stripes
- Caused by occasional channels where data are mostly, but not fully, flagged?
- askapsoft flagger should flag everything if more than some threshold
- Continuum subtraction also impacted by single-channel outliers?
- Data quality difficult to asses due to size of cubes
- 40 minutes to open in casaviewer
- Carta visualisation package being tested along with HDF5 conversion
- Discussion of optimal weighting robustness, tests of single beams with alternative options
|
| 10 min | GASKAP test observation processing | Chenoa | - SMC data has been bandpass-calibrated and visibilities delivered to ANU (first scheduling block)
- Self-cal failing, but perhaps not needed
- Second SMC field being transferred
- Same will be done for LMC data next week, disk space allowing
|
| 10min | RACS re-processing | Dave | - Using scripts designed to keep Galaxy queue filled automatically
- Estimates number of jobs needed by looking at the number of fields in a scheduling block
- Queue limited to 10,000 jobs, currently using most of these most of the time
- Might be good to leave a gap for other users
- Jobs tend to finish quickly
- Some blocks need more than 10,000 jobs! Need to split calibration and imaging
- Mosaicking still the longest step, needs about 40 minutes
- Dealing with occasional failures is very difficult with this many job numbers
- VAST likely to use a RACS-like pilot survey approach (over several epochs)
- Roughly half of processing pass two done (includes polar cap)
- Emil working on re-mosaicking to remove edge effects and HiPS conversion
- Stokes V MFS images will be made for processing pass two
