Minutes:

Introducing Garvit:

  • Intro to Garvit’s PhD project

    • Will be taking over from Nick

  • Nick no longer attending

General update (Ramesh)

  • No new observations taken

  • Changes to MWA observing semesters (2022A/2022B)

    • Lightning damage – down to 80 working tiles

    • 2022A pushed back to 2022-05-01

    • 2022A proposals include observations for timing PSR #3 and continuing MWAX commissioning (see below)

    • 2022B slated for September/October, but still might get delayed further

  • Progress of SMART TBD

    • Possibility of compressed campaign in October (fingers crossed), but only a small subset of orange observations

  • Science commissioning for 2022A

    • Extended goals, including

      • Picket fence mode

    • Amended target list to suit LST range (and commissioning goals, of course)

  • Plans and priorities

    • Existing papers → publish

    • Push forward on pulsar hunting (with SMART webapp) and finish first-pass processing

    • Advance MWAX commissioning

    • Plan 2nd pass processing

    • Follow up (timing, polarimetry, etc.) of PSR #3

  • Steven Tremblay may be making a comeback (based at NRAO)

SMART webapp demo (not live) (Sammy)

  • Sammy explained the SMART Web App demonstration!

  • Server - was down during the presentation.

  • Demo - was through screenshots.

    • Back-end : Postgres database 

    • Front-en : Django  

      • Authentication features as well

    • Possible to outsource the search for other people to login and test the candidates 

  • Nearing completion Beta Version  - testing session on Monday - Beta Version 

  • Manual Uploading of candidates - that is not automated yet! 

  • Features :

    • Data-Central - host 

    • Built in features :

      • Clustering/Cone Search : Cross correlating the meta information of the candidates across different beams! 

      • Optimized for finding good candidates faster!

        • Show Similar Known Pulsars and Similar Candidates 

        • Brings the good ones - clustered to the top of the list! 

        • Add notes - Apply rating/notes to every repeating candidates 

Discussion

  • SD:

    • How many people rank a candidate

  • SM:

    • Everyone would be able to rank the candidates 

    • Everyone’s average score would be updated accordingly - follow this list 

  • RB:

    • More than 3-4 people rank every candidate

    • Encourage students for ranking to improve and encourage their learning and understanding 

  • SM:

    • Looking to put Applications to scale up 

    • Deploy this product in High Schools! 

  • RB:

    • Deploy and outreach in High Schools 

    • In conversations with Data Central Team to keep this in mind to accommodate this deployment within a reasonable budget with the necessary training 

  • SM:

    • Need to submit an EoI by next month 

  • SD:

    • New PhD Student to help join in for the Pulsar Hunting session! 

  • RB:

    • Monday Evenings 6 pm : Pulsar Hunting!

    • Incentive : “Student’s Pulsar” 

    • Sammy to organize this training and testing session 

Sammy - Paper’s Update 

  • J0026-1956 Paper 

  • Working out of Overlead, working through the local repository 

  • Referee Comments: 

    • 20 minutes of “Null”

    • Manual Single Pulse Search performed 

    • Help Needed :

      • What is pdmp doing? 

    • Working on Nulling Histograms 

  • Two “non-detections” processed, found some faint single pulses

Discussion

 

  • RB: Max(SNR)

  • RB: We know exactly where the sub-pulse is. Does it make sense to add one more curve to the plot - where Pulse Energy is based on the sub-pulse? May/May not be obvious to people! So, that distribution plots are informative for a large number of people! Referee is not asking for details though!

Ramesh’s Paper Update

  • Survey description paper

  • Using Trello for project-managing

  • Includes

    • detections of known pulsars (gallery!)

    • figures to demonstrate tiling strategy

    • Plot to compare measured vs predicted flux density (Nick’s work)

  • To-do:

    • Several sections to be drafted, and accompanying plots to be made

      • Flux density analysis

      • Subsections on PSR #2 and #3

      • Survey simulations

    • Just need a block of time to sit down and write!
