LII The galactic longitude of the poiting position. The galactic latitude of the poiting position. Pixels value in detector coordinates of the pointing position. Pixels value in detector coordinates of the pointing position. 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.
This includes all dead time effects, interruptions in coverage etc. Offset The offset from the pointing position from the center of the detector. This parameter is usually 1-4 arc minutes because of a deliberate random offset put in to the pointing to avoid always the same spot on the detector being exposed by the source. 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.
