  • 21B
    • SRP
      • Panel Discussions. MarkClaussen reported no major issues. The AGN SRP needed one extra hour. AmyMioduszewski reported that SFM was a bit low during the first session but caught up in the second. There was some scoring issues (swapped reviews) in HIZ but this was resolved early on during the first meeting. DanaBalser reported no major issues but the SRPs went slower than ususal.
      • Finalize Reviews. DanaBalser reported that we are behind in finalizing the reviews. The current plan is to finalize the reviews on Friday. He will send an email to the TTA list when complete.
    • TAC
      • Large Proposal Meeting. DanaBalser summarized the schedule. We should receive the GBT Large proposal reports on 26 March 2021. The plan is to release info to the TAC on 5 April 2021 for the Large Proposal meeting on 9 April 2021. Currently there were no issues reported from the schedulers (ToneyMinter, AmyMioduszewski, MarkClaussen).
      • TAC Meeting. The TAC meeting is 19-20 April 2021.
  • 22A
    • PST CfP Requirements. LorantSjouwerman reported that there are no major new capabilites planned. We need to make LWA shared risk. ToneyMinter reported no known major items at this time; a new X-band recevier may be available but this should not be a big change. LorantSjouwerman will send around the links to the JIRA tickets. The plan is to prioritize items at the next TTA meeting. The deadline is 26 March 2021. We agreed that we need to organized tickets earlier in the process next semester.
  • GOST-->RCT. There was a lot of discussion. Here are the main issues. GOST is currently used by proposers to specify spectral line setups in the PST. It was an interim solution developed more than a decade ago until the RCT could be improved. The RCT is used to configure the correlator for observations, but the tool is difficult to use and there have been consistent complaints from our users. There was some concern about using the RCT for proposals given that our users tend to write proposals at the last minute. For various reasons GOST is difficult to maintain and does not accommodate some observing modes. Moreover it does not get some details correct. Therefore, we currently recommend that proposers use the RCT for some observing modes; that is, we have a hybrid approach. There is some concern that GOST will not work in the future (e.g., new version of Java though this may not been a problem). There was some disagreement about whether or not we should commit to using the RCT instead of GOST before the RCT is improved. We agreed that we should improve the RCT instead of GOST and that we need to push to make this a priority to upper management. That is, there is a risk that the software will fail in the near future. For 22A there was some discussion that we could start to encourage proposers to use the RCT, especially for complex spectral line configurations where GOST is not accurate. EmmanuelMomjian and LorantSjouwerman will discuss ways in which the RCT can be used in a more limted way (e.g., skip Doppler setting). We will attempt to converge on a plan at the next TTA meeting.
