Description:
    This  is a 3-part table presenting a  log of the IUE Fine-Error Sensor
    Observations of TY  Pyxidis in  November 1990.  In order  to determine
    accurate  magnitudes  from   FES   measurements,   a   focus   and   a
    reference-point offset corrections must be applied. The data presented
    in the paper  (Figure  1)  have  these  corrections  applied  and  are
    averages of two or more measures taken close in time.
