CHECK GAPS

CHECK GAPS

To run chk_gaps:

  • In a SOC window type: chk_gaps
  • Check previous chk_gap pages to make sure that any past gaps that were recoverable have been received
  • Any data that we should have but don't, SOCs fill out a request form (forms are in the front of the QKL binder) and give to Patty
  • Weekly (on Monday), edit /ftp/plan_files/Tlmgap.plan to change the start date of the program

    NOTE: If the Tlmgap.plan file has been filled with "junk" like this:

    knowledge base "/ftp/plan_files/Tlmgap.kb" at 2005/03/14 00:00:00 duration 10d

    resource data "/tmp_logs/gaps.tmp"

    begin forcing scheduling

    schedule most constrained first

    schedule "/ftp/iws_files/input_actplan/UVC20050321000.IAPr"

    schedule "/ftp/iws_files/input_actplan/UVC20050322000.IAPr"

    schedule "/ftp/iws_files/input_actplan/UVC20050323000.IAPr"

    schedule "/ftp/iws_files/input_actplan/UVC20050314000.IAPr"

    NOTE: this happens because someone most likely has hit "Save" at some point.

    Delete all the schedule "/ftp/iws_files/..." lines (nothing else), and it should still work. Deleting some of the other lines might result in chk_gaps not working, with an error message "Invalid input."

  • NOTE: The SWAN OBT jumps every few months and you'll see a gap in their data. Check the files in /ftp/tlm_files/SWASC and verify the timing glitch by looking at the science data files. Email Patty, Luis, George and SWAN about the problem but take no action.

  • To run chk_gaps manually, type tlm_times - this takes a while, otherwise it runs in the early morning through a cronjob
  • NOTE: During Keyholes be sure to cross check the gap times with the DSN schedule and the Keyhole schedule online at http://sohowww.nascom.nasa.gov/soc/keyholes.html or here to see which data set we are in (VGM, VGMF, VGMFL5, VGMFL6, etc) so all data gaps can be accounted for.

    NOTE: To see what is in the telemetry file, type tlmtool -f filename
