Table 1: Summary of observations. The rows designate the observation date (UT), the time since the explosion of SN 1987A on 23 February 1987A, the spaxel size of the observation, the wavelength range of the spectrograph setting, the spectral resolution, the total exposure time and the image quality as measured from the combined data cube on Star 2 and Star 3. We further list the standard star used for the flux calibration, and the uncertainty in the flux as determined from a comparison of Star 2 from the corresponding black body curve, the uncertainty in the wavelength calibration as measured from night sky lines and the corresponding uncertainty in velocity.
