DATA_SET_DESCRIPTION 
Data Set Overview
    =================
      ESO MultiMode Instrument has various spectroscopic options with
      large-field capabilities (up to 10 x 10 arcmin with a 2048**2 CCD).
 
      The scheduling of the observing programmes at the NTT can be adapted
      to the sky conditions. When the image size is better than 0.7
      arcsec, the telescope can be configured for observing with SUSI. In
      order to take full advantage of this unique capability, ESO has now
      introduced a special category of observing programmes which require
      exceptional seeing and are executed in a service mode by ESO staff
      when the sky conditions are favourable.
 
 
    Processing
    ==========
      The EMMI data are calibrated broad-band (Johnson B,V,R,I) images of
      Shoemaker-Levy 9 taken about two weeks before the impact.  They are
      calibrated for the construction of color-index maps,  which means
      that -2.5*log (pixel value) yields 'magnitudes per square arc sec'.
      The PI for the program is Rita Schulz with Joachim A. Steuwe and
      Mike A'Hearn as collaborators.
