Day Operations Procedures

The CCD linearity tests follow the hereunder procedure:

• mount beta lights in red, blue or susi filter wheels
• Update  filter column of EMMI or SUSI configuration panel .
• Make sure nasmyth shutter is closed.
• Switch off telescope floor lights.
• make sure MIDAS PCO is running.
• Start  one of the obd's

/insroot/SYSTEM/COMMON/TEMPLATES/OBD/BlueLin.obd,
/insroot/SYSTEM/COMMON/TEMPLATES/OBD/RedLin.obd or
/insroot/SYSTEM/COMMON/TEMPLATES/OBD/susiLin.obd
no parameter is needed.
At the end of the test, MIDAS-PCO will print several pages of text and graphic results.
Archive thein the CCD TESTS binder and check their consistency with the previous ones.
• Operation lasts between 25 ( Susi) and 210 minutes ( Emmi).
• In the case of EMMI , 6 modes are tested ( 2 binning x 3 speeds ) and 4 sets of results are produced per mode.
• The transfer and reduction of test results may be performed
• Do not forget to dismount the Beta light and update the configuration panel.
• In case of bad results,  inconsistency or any doubt  inform CCDScientist of NTT Team and ODT
