Dear all,

I installed the gating unit now more permantly at the experiment and
saved two new lens settings in our standard folder. I suggest to use the
setting

6kV_kmode_m4.2_30VTOF_453ns_focus_Gated_21.0V_FMCP.sav

now as de-facto standard. It maps more or less the complete
photoemission horizon, and is otherwise similar to our old x4 setting,
but cuts of the lowest ~3-4 eV of the spectrum.

Best, Laurenz
