MIPS Point Spread Function

Lefthand panel: This is a MIPS 24 micron image of a bright star. 2 frames totaling 6 sec of integration time were coadded, with cosmic ray rejection. The result is sampled at the native MIPS 24 micron array pixel scale of 2.55" per pixel.

Center panel: This is a shift-and-median reconstruction of the MIPS 24 micron PSF. 240 dithered frames, totalling 720 seconds of integration, were combined. The image is oversampled by a factor of four compared to the normal MIPS 24 micron array plate scale.

Right panel: Optical model PSF for the MIPS 24 micron camera, calculated with the SIRTF Tiny Tim software. As in the center panel, the model image is oversampled by a factor of four.

The Multiband Imaging Photometer for SIRTF was developed by the University of Arizona and Ball Aerospace Corporation, under the direction of Principal Investigator Dr. George Rieke.
