2014-03-05 CSPAD CxiDs1 alignment

Data for alignment

In order to get cspad geometry parameters for experiment cxib6714 Jason Koglin suggested to use cxi83714 runs 17,18, 127, 128, 130-132, 135, 136.

CSPAD array with subtracted pedestal and threshold 4*rms(per pixel) is averaged over 5000 events of run 136.

Parameters from latest optical measurement

center and tilt are used from /reg/neh/home1/dubrovin/LCLS/CSPadAlignment-v01/calib-cxi-ds1-2013-12-20

Tuned calibration parameters

offset_corr/0-end.data :

  0   0    4   4
  0   4    1   1
