Operations :

The CCD tests should follow the procedure:

• For EMMI:
• mount respective beta lights in red and blue filter wheels
• Update EMMI configuration panel with mouse on filter columns.
• Make sure B nasmyth shutter is closed.
• Switch off the EMMI room light.
• Start template ~emmi/emmi_setup/DIMDMT01.obd; no parameters are needed.

At the end of the test, MIDAS-PCO will display a graph with the Bias level, Gain, RON and flatfield intensity level parameters. Use this plot for checking that the values are consistent with the previous ones.
• Operation lasts 3200 sec.
• Do not forget to dismount the beta lights and update the EMMI configuration panel.
• For SUSI2:
• mount SUSI2 beta light in filter wheel
• Update SUSI configuration panel with mouse on filter column.
• Make sure A nasmyth shutter is closed.
• Switch off the SUSI room lights.
• start template: ~susi/SMT01.obd; no parameters are needed.

Both binning 2x2 (14 sec) and 1x1 (40 sec) tests have been merged into this new template, you don't need to execute the old ones.
A plot will pop-up on MIDAS-PCO, use it for checking the new parameters values against the previous ones.
• Operation lasts 1800 sec.
• Do not forget to dismount the Beta light and update the configuration panel.
• For Both test:
• The plots are found on wemmi ins:/midwork/visualize_emmi.ps or visualize_susi.ps
• At the end of both test, a fortran program is run automatically to create the CCD-parameters Webpage.
• The page is found on epu under the directory ~/nttoperations/refdata/param_ccd.html.new
• If the values displayed during the tests are satisfactory, on epu, copy the previous page into param_ccd.html.old, and move the new page as param_ccd.html.
• If the values are not satisfactory, don't make the change. Just notify the Web "master" that no update is available.
• AND in case of the latter: inform  CCDScientist of NTT Team  and ODT
