FOS/BLUE Wavelength-Zeropoint Correction Procedure Summary: A significant time-dependent systematic shift of up to 7 quarter-stepped pixels (1.75 diodes) in the zero-point of the FOS/BL wavelength scale has been confirmed in FOS Instrument Science Report (ISR) CAL/FOS-149 (Rosa, Kerber, and Keyes). ... Figures 1 and 2 (PDF - 14 Kbytes) illustrate the magnitude of the observed shifts and the effectiveness of the quick-fix algorithm provided here. ...

... This will only be implemented at a later time, if in-orbit experience warrants it. rgsoffsetcalc accepts a list of DIAGNOSTIC datasets (refer to the ODF ICD [ 1 ]. For each DIAGNOSTIC dataset rgsoffsetcalc calculates the mean and standard deviation of the pulse height distribution. ... Optionally, rgsoffsetcalc can store the pulse height distributions for each input dataset and node in a dataset (see the description of withhistogramset and histogramset ). ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...
