ASKAP Continuum and Polarization Data Processing Workgroup

 

 

 

The intention of this group is to bring together members of the ASKAP Science Data Processing (SDP) group and members of ASKAP science survey teams including EMU, POSSUM, VAST and anyone else who is interested in joining. 

 

Our current goals are to contribute to commissioning the end-to-end ASKAPsoft pipeline and to ensure that it is meeting the needs of our early science data requirements.  I encourage all survey teams to participate in this process since we are all reliant on the performance of the up-front stages of the pipeline. Use of ASKAPsoft is not mandatory, since anything we can learn about the ASKAP data and how to most effectively deal with it will be useful, but I encourage everyone to try out the end-to-end processing pipeline or at least to familiarize themselves with its capabilities.

Team Members

A list of group members will be maintained here

Please help to keep this page up to date and provide a little description of what you are actively working on.

 

 

Data Sets

I will compile a table below with candidate test data sets that I suggest we focus on.

I will link each data set to its own page so we can discuss our results and compare notes. 

 

Field Name  SBID  Cal SBID  Notes 
LMC  1997  1995  closepack36 footprint. only 30 beams ingested. A-B-C interleaving. 10+ hours.  48 MHz BW @ 1400 MHz
CDFS 2102 2099 square_6x6 footprint. 36 beams. A-B interleaving. 10+ hours.  48 MHz BW @ 1032 MHz
CDFS 2107 2104 square_6x6 footprint. 36 beams. A-B interleaving. 10+ hours.  48 MHz BW @ 1032 MHz

 

 

Results

 I created a directory on the Pawsey file system where we can share our scripts, imaging results, intermediate data products, etc.  

/group/astronomy856/askapdp

Please create sub-folders before contributing your results to help keep it organized.

 

 

Minutes

I will maintain a brief summary of each meeting below:

 

28Sept2016

At our kickoff meeting we talked about what our goals were for this group, which seemed very well aligned in terms of hands-on work and collaborative efforts.  Meeting weekly for about 45 minutes was widely supported.  It was suggested that we include some time in each meeting for hands-on work. 

 

We decided that for the next couple of weeks we would combine our efforts on the earliest stages of the pipeline, i.e., flagging and solving for the bandpass of the 1934 calibration observations.  We chose to take a close look at SBID 1995. Wasim and Josh will also work within ACES to propose a long (~8 hour) calibrator observation to better understand bandpass stability.
