Setting up the software and basic configuration

• I built the IPP software from svn trunk (r25003)
  • hit and fixed an issue with libreadline linkage vs libncurses (see ticket #1284)

• created an ippadmin database and ippadmin user (dropped existing empty ippadmin):
  • ippadmin init localhost ippuser ipp

• created an empty-password ssh key for use by the ipp user:
  • ssh-keygen

• set up the user config files:
  • cp src/ipp.20090805/ippconfig/ipprc.config .ipprc
  • cp src/ipp.20090805/ippconfig/site.config.in install/ipp.20090805.lin64/share/ippconfig/site.config
  • edit site.config to include db host, etc information

• install ippMonitor:
  • cd src/ipp.20090805/ippMonitor/
  • psconfigure --dbhost vysosdata1 --dbuser ippuser --dbpass (XXX) --htdocs /srv/www/htdocs
  • make (failed at first try because of permissions on /srv/www/htdocs)
  • ippMonitor was missing DB.php on the apache server -- see IppMonitor for the fix

Demonstration Data Analysis

• set up a demo database:
  • ippadmin project vysosdata1 ippuser demo_20090806
  • pxadmin -dbname demo_20090806 -create

• inject data (science, flat, dark)
  • ipp_serial_inject.pl --telescope vysos --camera vysos --workdir /home/ipp/data/demo.20090806 --end_stage reg --dbname demo_20090806 newdata/20090630/*.fts
  • ipp_serial_inject.pl --telescope vysos --camera vysos --workdir /home/ipp/data/demo.20090806 --end_stage reg --dbname demo_20090806 newdata/20090630/flats/*.fts
  • ipp_serial_inject.pl --telescope vysos --camera vysos --workdir /home/ipp/data/demo.20090806 --end_stage reg --dbname demo_20090806 newdata/20090630/Calibration/*.fts

• test that pantasks + ssh work:
  • ssh vysosdata1 pclient
  • you should see something like the following:

    pclient: no file /home/ipp/.pcontrolrc
    
    Welcome to PCLIENT - pcontrol client shell
    

• run the registration analysis on the new data:
  • start pantasks; in pantasks, issue these commands:
    • module pantasks.pro
    • module register.pro
    • {{{ add.database demo_20090806
    • control host add vysosdata1
    • run
  • register should run for a while; in ippMonitor, entries in 'newExp' should slowly move to 'rawExp'

• Generate Detrend Images
  • For now, the VYSOS5 config applies only bias and flat
  • start & setup pantasks:
    • module pantasks.pro
    • detrend.modules
    • {{{ add.database demo_20090806
    • control host add vysosdata1
    • run
  • make a bias:
    • dettool -simple -pretend -dbname demo_20090806 -definebyquery -workdir /home/ipp/data/demo.20090806/detrend -inst VYSOS5 -det_type BIAS -select_exp_type BIAS
    • look at the results in ippMonitor Detrend steps
  • make a flat:
    • dettool -simple -pretend -dbname demo_20090806 -definebyquery -workdir /home/ipp/data/demo.20090806/detrend -inst VYSOS5 -det_type FLAT -filter r -select_exp_type FLAT -select_filter PSr

Side note on astrometry

we were having trouble with astrometry in May. I've been looking into this a bit more, and it looks like at least part of the problem is that the angle moves around a bit, and the solution is sensitive to angles of 1-2 degrees. The file ippconfig/vysos5/psastro.config includes an option for searching over a range of angles (PSASTRO.GRID.MIN.ANGLE, PSASTRO.GRID.MAX.ANGLE, PSASTRO.GRID.DEL.ANGLE). I've set this to -10 to +10 in steps of 1 degree. This may not be enough range in some cases.
