Selector.C can be used to adjust energy bad reconstruction in the EXL detectors due to energy leak (see the PDF attached for more information about it)
once we already have the coefficients for the energy on EXL crystals. To operate with it, for first calibration coefficient must be deduced. Once it is
done the slopes and offset of the calibration have to be inserted in Selector.C file at lines 41 (a[19]) and at line 49 (b[19]). After thqt thresholds |

They succeeded to get 90 % transmission with CSS1 but the energy at the exit was changed by 4%, that is not compatible with the CSS2 limit of 1 %. After
fitting the CSS1 energy they obtained 70-80 % transmission only, but it is enough. The problem with the HF of CSS2 was solved. They are trying to accelerate |

|
In case of problems in the run control, if it is not possible to reinstall the crates in the "Ready" mode status,
it is possible to reboot them remotely via the software commands.
this can be done using the iolan windows.

After correcting position for the Must2 detectors by taking into account the real hit position on the target that was (0,15cm,0) and not (0,0,0). The way
to do it was to artificially move every detector 15cm lower.
