The SED FPS etermines the position and orientation of the SED slit relative to the PCRS.
The goal of this task is to estimate the location of the SED prime frame with repsect to the telescope boresight. However, we do not observe at the prime frame, we use the CSMM with a chop amplitude of at least 1 arc minute peak to peak or +/- 0.5 arc minutes from the central mirror position that defines the "on" beam.
The location of the MIPS instrument frames are found in the frame tables and are given as brown angles. In order to estimate the instrument pointing frame (IPF), a combinations of spacecraft moves and mirror motions places the star on several locations on the array. In addition, these observations are "sandwiched" between observations of stars with the two PCRS. The MIPS team calibrates data and centroids the star on the slit. These centroided values are passed to the IPF team who uses observations of stars with the PCRS to provide the final calibration and estimate brown angles need to locate the instrument frame.
Telescope went into suspend mode - no data.
