Peakup Tracking by AOR

This page provides a list of AORKEYs associated with peak-up failures or false positives. Each AORKEY is a link to two plots illustrating the problem. The left plot is an acquisition image and the right plot is a Sweet Spot image. See the IRS Instrument Handbook for a description of the peak-up acquisition algorithm. Each plot is 43 by 43 arcseconds. In each image, the square indicates where the intended peakup target should have been. The circle indicates the position of the brightest centroid in the frame.

(does not include AORs affected by CE anomaly in IRS49)
