172 Run 44762 was measured with a Hg lamp on the test "Chessy" sample to calibrate FoV in µm in the PEEM mode.
173
174 Runs 44798 and 44799 - optical spot profile measured in PEEM mode under the same settings as run 44762
175 with two different attenuations of the pump laser to determine the spot size of the pump laser.
176 This is needed to estimate pump fluence during trMM runs (44824, 44825, 44826 and 44827) using values
177 of I,,0,, monitor of the pump laser.
178
179 Runs 44797 - measured with 36.2 eV in k-mode with manually variable sample bias from 28 to 32V by 1 V 
180 every 2000 shots to calibrate the energy scale.
181 This energy calibration has to be used for trMM data.
182
183 Runs 44824, 44825, 44826 and 44827 were measured (% style="color:#333333" %)from Gd/W(110) sample which was pumped with
184 a 1030 nm s-polarized optical laser and probed with 36.2 eV for time-resolved momentum microscopy (trARPES)
185 varying the time delay between the optical laser and FEL. The time delay was changed in ZigZag manner repeatedly
186 from 1462.00 ps to 1464.85 ps with 200 steps and 1 sec waiting time at each step.
