2. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 Mission #1: calibration completeness (“save last night”) calibrations incomplete: science OBs to be repeated focus on calibration plan: –known, predictable, configured –can be checked automatically calChecker 1. Setting the stage

7. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 evaluates each box in colors: –green (OK): all calibrations complete and within validity (e.g.: 5 BIAS & 3 FLATs & 1 ARC & 1 STD within validity) –yellow (NOK): calibrations complete but some outdated (e.g.: as above but 3 FLATs are 2 days old) –red (MISS): calibrations incomplete, at least one missing (e.g.: 5 BIAS & 3 FLATs ok, 1 ARC & 1 STD missing) missing or outdated calibrations are indicated

8. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 links to details –for each box: complete list of science files –prog_id, obs_id etc. for easy reference –OB grade and comment: useful for analysis

9. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 ANALYSIS –QC scientist to provide analysis/comments, but this requires interaction (  not always available!) –may override tool NOK/MISS results BOCAL, EOCAL –signal about daytime calib queue –calChecker displays “pending”, “ongoing”, “finished” for current date

10. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 called: once per hour by cronjob –has update information, knows about its age don’t hesitate to contact QC!

11. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 documentation association rules contact planned: –include ticket mechanism (PSO scheme) –memory function for long-term calibrations (once a month etc.) and HC calibrations

12. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 general rule: calChecker follows calOBbuilder not planned: –short-term night calibrations (like standard stars within 2 hrs) –complex dependencies (multiple standard stars a night; alternative calibrations; calibrations for calibrations) to be done on Paranal: –optimize calOBbuilder queue (input provided by QC)

20. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 HC monitor: selected scores selection: “relevant for instrument health” AB product monitor: all scores of a date

21. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 score propagation: –data scores for last week only –plot: last data scores summed up plot score green if last data score is green (previous red scores ignored) report score: plot scores are aggregated in report score report scores in group scores, and finally in instrument score all higher-level scores turn red if at least one lower-level score is red

22. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 big advantage of score hierarchies: within a second –instrument score green  you know within a second: all is OK! –red: the score overview can tell you more scheme intended to guide you to issues

23. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 Health Check monitor –update pattern: refresh most important ones upon new opslog data –less important ones at least once per 24 hour process health –monitored: opslog transfer, parser (1x per hour) –coming soon: data transfer, ngas access

24. Improved and automated QC process [calChecker] [HC monitor] [histo]calCheckerHC monitorhisto April 27, 2009 planned: –defocus the OPSLOG data (to become a fallback solution except for VIRCAM/OCAM) –improve update pattern for HC reports (immediate after new data) –product quality links (same as for calChecker) –agree on mail alert mechanism
