'''eSASS Q&A'''

  * [[https://wiki.mpe.mpg.de/eRosita/SuggestionsforeSASS|Suggestions for eSASS]]
    * flux (and column) units in ermldet / catprep are missing (only missing in catprep?)
      don't use '/' in units, standard is, e.g. s**-1 (OGIP standars?) 
    * HR values are missing in 945 processing (check 946), check hrdef parameter 
    * evtool: WCS issues in DS9 display (Ian discussing with Werner>)
  * [[https://wiki.mpe.mpg.de/eRosita/DATool/SuggestionsforDATool|Suggestions of DATool]]

'''Weekly eSASS developers meeting'''

  * NRTA
    * eSASS task & caldb versions / time shift alerts

  * 946 processing
    * many TM4 GTI / duplicated TM4 events, effect on GTI? Plot of duplicate TM4 events over time?
    * under-exposed sky tile corners - check telgti version in pipeline eSASS

  * evprep: 
    * check for missing frames and adjust GTI
    * incorporating onetools into evprep (new cal file) - done (in task archive, caldb file exists)

  * evtool / srctool region angles, Ian+Jeremy will investigate / Ian will test removal of '-' sign

  * ermldet: HR ratios
  
  * DAtool
    * Accessing 946 / eRASS:2 products
    * Region requests issues
    * HealPIX maps
    * Wiki description / dedicated meeting?

 * Background analysis: projecting closed data onto the sky (XMM ESAS) - dedicated meeting?
    * define algorithm, identify who will implement it 

 * User requests
   * DAtool: providing large multi-sky tile images - Jeremy will share his Python script with Alain and Sabine
   * DAtool: Requesting sky tiles by galactic coordinates (Werner Becker)
   * Orbit file access (Axel Schwope) - use caldb download script
   * Cumulative attitude file (Jürgen Schmitt) -  GL will make script for merging intermediate attitude, then put in crontab
