ESO  New  Technology  Telescope CCD Page Update Instructions

Note: These instructions are for NTT Team operations.

Updating the CCD Database

 
• Run the linearity OB: RedLin.obd, BlueLin.obd or susiLin.obd.
• Instructions for running the tests are available on nttoperation intranet.
• from now on the the updating script forceUpdate is automatically run on nttweb@www.ls.eso.org
  therefore the rest of the page is just needed by people who want to do it by hand for instance after eliminating bad data.
  
  • The standard test will have generated numerous files. They'll have been transferred automatically by the template.
    ( This can also be done manually by simply typing: to_www CCD_Number yymmdd speed
    where CCD_Number is  31, 45, 46 or rX#*, yymmdd is the date the test was run and speed is fast, norm or slow .
    • *- r for red CCD[ #62 A&B (right) and/or #63 C&D (left)]
    • *- X= A,B,C or D , CCD stripe counted from right to left.
    • *- # = 1 or 2 , binning. )
  • Telnet to www and login as nttweb

    
    NEVER DELETE ANY FILES ON www !

  • On nttweb@www, issue the command:

    
    update CCD_number speed
    where CCD_number is the identity of the CCD. (To get a list of currently supported CCDs, simply type update and hit return.)
    You will see a data file appear on the screen. Check that the most recent entry has been added, and the values look reasonable. Please note that there is no problem in executing the update command for any CCD again as it will just take the last data and re-generate the page as it already is. If there is a problem contact NTT CCD scientist.

  • The script will work for a couple of minutes, and finally produce an updated page. Please load the page into a browser to ensure all has worked.
  • if and only if all the results of all amplifiers of all the modes were OK ( 24 results for EMMI red, 3 for EMMI blue)
    on emmi@wemmi or susi@wsusi
    cd /data/SPC/CCD_StdMakeAllLog/
    CCD_StdMakeAllLog
    This will replace the pages
    http://www.ls.eso.org/lasilla/sciops/ntt/CCDs/CCD_std_EMMI.html
    or
    http://www.ls.eso.org/lasilla/sciops/ntt/CCDs/CCD_std_SuSI.html
    with the last measured values of CCD parameters.
