Development

• Calibration and Flagging
  • N/A
• Imaging
  • N/A
• Data Visualization
  • N/A
• Import / Export
  • N/A
• Infrastructure
  • N/A
• Simulation
  • N/A
• CASA 6
  • What is the formal modus-operandi for developers to get fix or development tested-validated and PR'ed ?
  • Documentation: examples with "import..." (potentially many and very spread throughout the docs) would need updates and decisions on what should be public or not. For example, flagdata says:

        import flaghelper as fh
        antdic = fh.readAntennaList(antfile)

Build / Testing

• Infrastructure

User Liaison Updates

• Helpdesk/feedback users:
  • Frequent crashes CASA 5.6.0 on OSX 10.13.4 (ALMA 16093; Adam Ginsburg)
  • CASA commands do not work on Samba-mounted drive (ALMA 16103; Adam Ginsburg)
  • In mstransform with multiple MSs, and when specifying both regrid=True and timeaverage = True, the resulting flux and velocity width of the line are wrong (possibly because not all of the spw’s have correct Doppler tracking applied) (ALMA 16021; Ian Czekala)
  • CASA 6 with Python 3.6 could not import libraries when using scipy 1.2.1, only with scipy 1.3.1 (Casey Law).
  • Since most people start with a virgin ~/.casa tree, it would be very useful to have a (commented) version of the init.py and rc file that can be placed in the ~/.casa tree. I would suggest to add examples of those in the $CASAROOT/etc or data directory, or share? (Peter Teuben)

Pipeline Updates

• N/A

Single Dish Development (8/22/19)

• Wataru Kawasaki
  • Wrote sample codes using PySpark and Dask to fit/subtract polynomial baseline from SD spectra as part of CNGI study
  • Used parquet as input data format
  • Elapsed time for baselining looks linearly scaling both for PySpark and Dask
  • Dask is a bit (about 50%) faster?
  • The codes yet to be parallelised. Partitioning parquet data needed in advance?
• Takeshi Nakazato
  • 5.6 closeout
  • 5.7/6.1 planning
  • investigating resurrected debug message in recent prerelease package -> created CAS-12641
• Renaud Miel
• Suminori Nishie
  • Working on CAS-12510 Refactor PointingdirectionCalculator _GTest.
  • Totally replaced to new desigen. Deleted obsoleted class and code. code size decreased by -1k Loc.
