Data Quality Operations¶

Observer2's role is to man the astro-chair: whereas the sispi driver is more closely focused on plumbing, guiding, and telescope interactions,
the astro-chair is more closely focused on the data as astronomy data.

1. making sure data quality monitoring tools are operating,
2. monitoring data quality and reporting it in the ELog,
3. filling out one or both of the Night Summaries,
4. creating new Data Quality tools, and
5. assisting Observer1 as needed.

Things close to observer2's heart:¶

1. Is the telescope still there?
   • be the one that goes upstairs during the dome flats to make sure the flat LEDs are on
   • every day take a walk around the telescope: just after sunset is a good time
2. Where has obtac taken data tonight, and what is the rate of good quality data?
   • run the Navigation plot. ( Using GuiderPlots and Navigation )
3. How goes the SN observations: what is the state of the deadman switch?
   • look at last night's night summary plot of SN gaps. ( http://decam03.fnal.gov:8080/nightsum/ )
4. How does the data taken tonight compare against survey data quality ideals: seeing, whisker length / ellipticity, background cnts/sec?
   • watch the strip charts of Quick Reduce (This is the "Observing History button": QR Description)
5. Are the calibration data ok?
   • check one/filter of the flat fields visually for saturation of other weird effects, using kenttools prompt> load ( Introduction to kentools )
6. Is the pointing ok?
   • run kenttools center on images, prompt> center, ( Introduction to kentools )
7. Is the seeing ok?
   • run kenttools seeingall on images, ( Introduction to kentools )
8. What is that beautiful object?
   • run kenttools prompt> ned, ( Introduction to kentools )
9. Keep it up all night long?
   • kenttools prompt> inv; load; center; seeingall ( Introduction to kentools )
10. Do the cognoscenti know what is going on?
    • comment in the elog, ( ELog Instructions on doc-db )
11. Does CTIO know what happened during the night?
    • work the draft of the CTIO night report ( CTIO Night Report Instructions)
12. Does the world of the DES know what happened during the night?
    • work the draft of the night sum ( Night Summary Instructions )
13. But there is that nagging issue I want to understand...
    • use the QR database to get image parameters ( How to query the Quick Reduce Database )
    • use the SISPI database to get instrumental, telescope, environmental parameters ( How to query the SISPI Database )
    • plot using ipython (recommended). Place in elog.
