LII The galactic longitude of the source. The galactic latitude of the source. The X value ranges between -1024 and 1023. The Y value ranges between -1024 and 1023. This is listed as yr.day, where yr is the last two digits of the year and day is the day of the year e.g., day 300 of 1984 is 84.300.
Times are accurate to the nearest second.
Some observation were carried out with an OBC program that sets a 'diamond' filter. This filter electronically screened out the outer part of the field of view. The resulting image, which is shaped as a diamond, covers only a fraction of the 2 X 2 deg. The source position offset given in arcmin. This includes all dead time effects, interruptions in coverage, etc.
