UVB-arm flats with spare part QTH lamp show a new spectral gradient and only 60% counts. Affected UVB-arm flats have been discarded [2018-05-03 ... 2018-05-06]. Calibrations from 2018-05-03 are tagged NOK in the sense, that the time match rule is slightly violated. No further action concerning calibrations for 2018-05-03 is required.
The following keys are used to define a SCIENCE XSHOOTER setup: INS.OPTI2.NAME (= IFU/SLOT) INS.OPTI3/4/5.NAME (= slit width for different arms) (since 2011-12-07: not for 5 arcsec slits) DET.WIN1.BINX/Y (= binning along x/y axis; UVB and VIS only) DET.READ.CLOCK (= readout mode; UVB and VIS only) DET.DIT (= exposure time, NIR only) DET.NDIT (= number of averaged exposures, NIR only)
