To measure the pixel locations (i.e. array orientation, scale) as a function of scan mirror angle for the 70 micron wide field array. The goal of this task is to estimate the location of the 70 micron prime frame with repsect to the telescope boresight. 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 70 micron array. 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.
We calibrated the data with the DAT and used IPD3 to centroid the images.
However we could only centroid 1 and 1/2 columns of data (the FPS is set up to generate 3 columns of centroids). This data set was not adequate for the IPF team to analyze.
