Description

This page contains instructions on how to run the Daily Health Check at the 2p2:

• 1) execution of the OB
• 2) data reduction
• 3) data publishing via the web
• 4) data verification

Execution of OB

On w2p2oh at the RITZ login as service:

Then either:

• (a) start up p2pp with the userid=51021, and run the DailyHealthCheck OB
  (do not forget to move away from the BtLght once finished, e.g.to the V filter);
• or (b) with the OT select from the Calibration Queue
  the OB named WFI_Daily_Health_Check, and execute it.

This will create two bias frames followed by two beta-light frames.

Data reduction

On the w2p2off machine login as user astro:

• Copy the images from /data/raw/yyyy-mm-dd/ to /data/reduced/Daily_Health_Check/
• Rename the images WFI_Dark.n.fits and WFI_Dark.(n+1).fits to wfi0001.fits, wfi0002.fits,
  and WFI_Ima.k.fits, WFI_Ima.(k+1).fits to wfi0003.fits, and wfi0004.fits.
  The first two are the biases, and the second two are the beta-lights.
• Start MIDAS: inmidas -p 66
• Set the context: set/con wfi and just hit return to the mask1 query
• Run the Daily_Health_Check script: @@ Daily_Health_Check 01 This will take some time.
• Run the script: DHC2epu + epu password.

This sends the DHC.LOG file to the t2p2web account on epu and
puts it in the directory: /home/t2p2web/DHC/ccdplot/

Data publishing on the web

On epu as user t2p2web:

• Run the script: updateDHC.pl
  This will create the gif files and transfer them to the appropriate directories.

Data verification (quality control)

Go to the WFI CCD page and check that the RON, bias level,
and flat field values, for all chips, follow the trend of
previous values.
