The sensitivity calibration was performed in air for VIS, in air and vacuum for MUV, and in vacuum for FUV.  The VIS and MUV experiments performed in air were done with the instrument pointed at a reflectance screen with the lamp at varying distances and for different lamps.  After data was taken, the direct illumination of the screen was occulted and then data was taken again to account for stray light in the lab.  Next the telescope was closed and data taken in order to account for dark counts with the instrumemt.  These last two data sets were subtracted off from the original data set.  For the MUV and FUV vacuum experiments, collimated light from a deuterium lamp point source was sampled by both the instrument and calibrated detectors.  Note the difference between "MUV_sensitivity_Moby2" and "MUV_sensitivity_Moby3" is that the instrument was rotated 90 degrees about the optical axis, and similarly for "FUV_sensitivity_Moby2" and "FUV_sensitivity_Moby3"
