• Preprocessing / NRTA
• Pipeline / ongoing processing

  • processing wiki page

  • 947
    • eRASS1 100 eROday DET chains
      • source catalogs
        • missing hardness ratios
          • mixed processing versions?
          • less cluster detections than in previous versions!
            • confirmed by Georg and Teng
            • SCUT/ECUT?

Edit conflict - other version:

• vs eFEDS ero100 vs eFEDS

• announcing merged catalog to full team (erosita-members)

• erbackmap in (almost) empty fields

  • hanging erbackmap runs (killed after >500minexecution time): sky tiles 139057, 037165

Edit conflict - your version:

• run eFEDS CalPV in 947 pipeline
• running Teng's pipeline on a shallower version of eFEDS
• comparing 946/947 eRASS1 clusters in eFEDS field
• vary task parameters in selected fields
• check pipeline script

• announcing merged catalog to full team (erosita-members)

• erbackmap in (almost) empty fields

  • hanging erbackmap runs (killed after >500min execution time): sky tiles 139057, 037165

End of edit conflict

• pipeline issues / log file access
• SOU chains / srctool

• CalPV data

• 946
• 001 (RXJ 1605)
  • TM5/ are missing (caldb version mismatch)

• eSASS tasks eSASSdevel page / Error tracking page

  • prexec
    • now prevents 'hanging' START_... parameter files
  • param
    • how to handle concurrent log file accesses
      • finetuning wait time?
      • one pipeline log file per machine?
  • from previous meetings:
    • ermldet
      • Mara: RA/DEC/RADEC_ERR contained -999 (ermlet-1.47?) Julien will report details

        • Georg didn't fin -999 but just null values. Happens only very rarely. <- resolved

    • ftfindhotpix / caldb

      • Konrad's proposal (discarding/renaming flags) - should not break backward compatibility -> after 947 is out

    • evprep
      • Konrad provided scaled threshold map
      • dedicated meeting of Konrad and Ian
      • Susanne should put new threshold maps in
      • will only affect data after 47036 (is in eRASS4) - not need for eRASS:3 reprocessing
      • Update needed to address issue with bad pixel neighbours - could be implemented before eRASS3 947 reprocessing (see previous meeting)
  • License files (once again)
    • Correct name of license file?
    • Jeremy/Alain/HB/Johannes(?)/Bamberg(Sixte?) to discuss and make final decision
    • Jeremy will look how/whether the individual task authors are listed in SIXTE
  • New user release
    • Test version by Ian
    • Reporting version number in user release (method by Philipp Weber)
  • recent task updates:
    • srctool-1.69
    • prexec-1.10
    • eroio-2.68
    • ermldet-1.50
    • param-1.42, 143 (not yet in sw_archive)
• HiPS maps
  • computing resources
    • Java / FTOOLS
    • Update frequency / rates images made by pipline?

  • Backend
    • delivering 947 products
    • version numbers in file names
  • Frontend
    • emails
      • short term: change email text (HB will provide text)
      • delete button
      • full text link under buttons (data / delete)
      • medium term: send second (confirmation) email from backend
    • Request log:
      • links to region files
    • Deleting old (older than 3 months) request direcctorys
  • access privileges for www/DataRequests (Harald)

    • DataRequests dir should be group eroproc with no world read access

• Script to obtain sky tiles (Miriam)
• Longterm activities

  • [?] Moving task archive to git

  • evprep

    • [9] evprep: space invaders event flag

      • implemented - should be documented in next users release
      • more detailed, quantitative checks regarding improvement of data quality
      • evtool should update the gti according to this flag
        • wider issue: should discarded frames due to flag selection b tracked in GTI?
    • BTI/GTI:

      • [7] one PDF per eRASS in wiki

  • [7] PSF normalization

    • caldb vs. shaplet PSF (Antonis)

    • may be necessary to put 1 arcmin vs. 4 armin flux correction into shaplet caldb file (needs testing) -> longterm activity

    • ermldet

      • [3] Johan's proposal? Georg to discuss with Johan (long timescale project)

      • [7] Proposal by Florian: don't use fixed extrction radius but one dependent on flux

    • Time dependent RMFs/ARFs (srctool?)

      • [8] RMF

      • [7] ARF

    • [1] EV_WEIGHT: event based vignetting correction (would require dedicated tests)

    • [6] Background analysis: projecting closed data onto the sky (XMM SAS)

    • [6] ersensmap: implement pointing PSF

    • [3] ftfindhotpix: test and update algorithm

    • [1] Light leak in eSASS/pipeline?

    • [1] DAtool: filtering catalogs?

    • [6] add option to provide larger sky areas (Jeremy's script)
