IRS Point Spread Function

Two false-color images of the Infrared Spectrograph (IRS) Blue Peak-up point-spread function. The image on the left is a single, six second integration on the normal peak-up pixel scale of 1.8 arcseconds per pixel. The image on the right is the co-addition of 18, six second integrations, re-sampled onto a finer 1/4 scale pixel grid with 16 pixels for each true IRS pixel. Both images are linearly scaled in intensity. The wavelength coverage of the Blue Peak-up filter is 13.3 - 18.7 microns.

The principal investigator of the IRS is Jim Houck of Cornell University. The IRS was designed and built by a team of astronomers and engineers at Cornell University, Ball Aerospace, and NASA Ames Research Center.
