2021-09-28 the maximum OPD is calculated on the 6 baselines. Specifications mentioned a maximum shift of 100 microns/8h for MATISSE-LM and 300 for MATISSE-N. F [qc_matisse@eso.org]
The averaged OPD is calculated per baseline for the different input raw files.
The maximum of the averaged OPD for the 6 baselines is plotted here.
Specifications are 100 microns/8h for MATISSE-LM and 300 for MATISSE-N.
The OPD must be stable to 20 microns to achieve less than 1% contrast loss during the night.
The max OPD for each baseline is plotted under OPD_LM and OPD_N (both for OUT-OUT and IN-IN configurations of the BCD)
