  • TCS:
    • Fixed a small ECS problem with Petr.

    • Continue to work on Olga's sky flats wiki Python program.

Last week
  • OT
    • #IT7560 getting the 2MASS image to work again (done)
    • Working on getting the latest OCS code to work with IntelliJ (done)
    • Find a way to pass tile size on image catalog query in subwindow. Not possible without mayor coding, found an easier way using the jsky catalog library configuration. (done)
    • #IT7441 subwindowing for LBC chips (ongoing)

  • LUCI
    • #IT7743 incomplete fits files. GEIRS connection issue with camera.
    • #IT7746 In the code it looked like we were waiting for an IIF command, then it turned out, thanks to Petr, we weren't catching an ICE timeout and now it looks like, the change in behaviour might be due to the new ICE interface version. Although, catching the timeout exception would have been a good idea no matter what.
    • Also looking at Docker for building/running TCS and MCSPU simulators and also for other possible uses. I.e. could it work for setting the LUCI software in the luci backup machine?

This week
  • OT
    • #IT7441 subwindowing for LBC chips
    • #IT7074, #IT7192 Issues related to ARGOS and ARGOS guide stars and also the way OT handles errors.
