    r3076 r3077  
    1919    - take all pixel areas out of MGeomPix::GetA(), remove all previous
    2020      areas
     21    - calculate photon fluxes from blind pixel and PIN diode, use
     22      area only to fill the conversion factors in MCalibrationPix
     23
     24
     25  * mcalib/MJCalibration.cc
     26    - display of number of photons for Blindpixel and PIN Diode Method
     27      changed to display of photon flux which is the actually
     28      calculated quantity
