153 +Run 44762 was measured with a Hg lamp on the test "Chessy" sample to calibrate FoV in µm in the PEEM mode.

155 +Runs 44798 and 44799 - optical spot profile measured in PEEM mode under the same settings as run 44762
156 +with two different attenuations of the pump laser to determine the spot size of the pump laser.
157 +This is needed to estimate pump fluence during trMM runs (44824, 44825, 44826 and 44827) using values
158 +of I,,0,, monitor of the pump laser.

160 +Runs 44797 - measured with 36.2 eV in k-mode with manually variable sample bias from 28 to 32V by 1 V 
161 +every 2000 shots to calibrate the energy scale.
162 +This energy calibration has to be used for trMM data.
