Other Pre-flight Analyses

• LETG PSF - /data/letg1/olive/letg_psf
  
  
  • entirely completed memo available here
    
    
  • possibly useful PERL scripts for automated MARX and SAOsac raytracing at /data/letg1/olive/letg_psf/*.pl
    
    
  • somewhat crappier IDL scripts for automated analysis of dispersion and cross-dispersion profiles at /data/letg1/olive/letg_psf/SIM/SIM/*.pro
    
    
• Mg-test - /data/letg1/olive/mg_test
  
  
  • memo describing analysis is at /data/letg1/olive/mg_test/XRCF/memo.ps; believe analysis is complete, memo lacks conclusion only
    
    

OAC Analyses

"Yes, it's the holiday we have to celebrate beating the Germans in World War I." - B. Wargelin, 11/99

• Extraction Region Efficiency - /data/buffy/letg3/olive/LETG_OAC/Wads
  
  
  • - MARX simulation with wads of counts at wads.dir
    
    
  • - current flat segment efficiency data at FlatSegment/efficiency.dat
    
    
  • - IDL code used to compare total counts to counts within the extraction region is at Pro/wads.pro; it's currently set for the straight segment region used in the processing.
    
    
  • - webpage describing analysis and results for parabolic region, which are linked from Brad's background pages, is here

Miscellanea

You know what they say about law and sausages: if you like either, you shouldn't watch them being made. Add science to the list. -V. Kashyap, 9/00

• list of all LETG observations to date is at /data/buffy/letg3/olive/MPlist/letg.html; SQL script to generate that file is /data/buffy/letg3/olive/MPlist/olivia.sql;
  to use it:

  setenv SYBASE /soft/sybase
  sqsh -Ubrowser -Pnewuser -Ssqlocc -Daxafocat -i -mhtml
  
  (The new file will overwrite any existing letg.html.)
  

  
  
  

am big fan of uk astronomy vs us, in case you hadn't noticed, but you won't see the difference until there, and will no doubt loath the uk altogether after about 6 months, possibly less. - J. Drake, 8/00
