Dark run calibration can be done with procedure calibman (since ana-0.13.18). Files can be deployed in the expected place, for example

Runs of Start calibman, click on tab "Configuration" then on tab "Parameters" and set field "end:" to 100000 and field "scan" to "2000". After that regular dark run calibration should work. Do not forget to coise the detector ANDOR. The same trick with event numbers can be acheived in the calibrun command skeeping empty 1195 events: calibrun -e sxrg3715 -d ANDOR -c ./calib -P -D -r 46 -n 100000 -s 1195 or calibrun -e sxrg3715 -d ANDOR -P -D -r 46 -n 100000 -s 1195 or calibrun -e sxrg3715 -d ANDOR -P -D -r 46 -n 100000 -m 2000 |

This algorithm does not improve image quality. Close consideration shows that the mean intensity value of each row of pixels is consistent with zero. The RMS spread il low for "green" horizontal stripes and larger for "color-full" stripes.
