EPICS camera information

• Camera info:
  model_nameListFACETProf.m in https://www.slac.stanford.edu/cgi-bin/cvsweb/matlab/toolbox/?cvsroot=LCLS

• Camera orientations: hard-coded rotations in:
  profmon_grab.m in https://www.slac.stanford.edu/cgi-bin/cvsweb/matlab/toolbox/?cvsroot=LCLS
  For example there is code like:
  
  

  Code Block
  % Set rotated image for CHER cameras. isRot=ismember(pv,{'CMOS:LI20:3506','CMOS:LI20:3505','CMOS:LI20:3515'}); props(isRot,17)=1; % ... and flip CMOS camera which does not have a :Y_ORIENT PV isFlp=ismember(pv,{}); props(isFlp,9)=1;

Global shutter for background data

• IMPORTANT: the shutter affects the beam globally, call ACR before putting shutter in
• Information taken from:  https://github.com/slaclab/facet-matlabTNG/blob/master/F2_DAQ/F2_runDAQ.m
