 Generating dark current PDFs from IV scans

1) Make a directory on RCF where you plan on putting the IV scan files (/star/u/you/IVScanFiles/)
2) Log in to daqman. If you don't have gateway access or are having issues logging on, see here.
  • $ ssh -A you@rssh.rhic.bnl.gov
  • $ ssh stargw.starp.bnl.gov
  • $ ssh -A -X -t evpops@daqman
3) Get the IV scan output files
  • $ cd /RTS/data/epd/
  • $ scp epd_ivscan_20**_**_**_**.log you@rftpexp.rhic.bnl.gov:IVScanFiles/
4) Get off daqman and back into "standard" RCF (what would you call that, anyway?)
5) Copy the code to generate the root files and PDFs, then run them
  • $ cd IVScanFiles/
  • $ cp /star/u/adams92/EPD/IVScan_Master/*.C .
  • $ root 'ivscanconvert.C("epd_ivscan_20**_**_**_**.log")'
  • $ root 'DrawIVhistos.C("ivhist_run_**_**_**_**.root")'
6) This generates a bunch of PDFs; bring them to your laptop
