• Results of ImgAlgos.NDArrCalib well reproduce cspad_mod.CsPadCalib

• Common mode correction shrinks the width of averaged intensities from 0.60 to 0.54, and rms from 3.78 to 3.27.
• Algorithm is quite time expensive, it takes 30-40ms/event.

Example of ImgAlgos::NDArrCalib for Fccd960

• Calibration

To calibrate fccd960 for dark runs use command

calibman

For test purpose a couple of dark runs were processed and constants were deployed:

Content of: /reg/d/psdm/XCS/xcsd7814/calib for detector: Fccd960
    Camera::CalibV1    
        XcsEndstation.0:Fccd960.0    
            pixel_rms

• Access data in psana

Example of the configuration file for psana psana-xcsd7814-r0079-fccd960-aver.cfg can be processed by the command

psana -c psana-xcsd7814-r0079-fccd960-aver.cfg

Two averaged images are saved in the text files for exp=xcsd7814:run=79 for raw and calibrated (subtracted dark level) data.

Gain bit coded gain factor 8 is applied automatically.
