Task Outcome Summary

Abstract

This is the routine 160µm flux calibration with a stellar source. The target was HD 131873. The data were obtained as expected, but I have flagged them as "anomalous" and the task outcome as "failure" because the 160µm filter leak (cf. G. Rieke's Nov. 19, 2003, memo) prevents the data from being used for flux calibration. Once the calibration at 160µm is achieved through other sources (like asteroids), these data can be used to calibrate the magnitude of the filter leak.

Analysis

The data were reduced with version 2.50 of the MIPS DAT. The non-default parameters used included turning off the correction for electronic nonlinearity, specifying the dark and illumination correction for campaign X1, and specifying the 160µm parameter file. The data were combined using mips_enhancer, turning off rotation and subpixel sampling, rejecting the first DCE after each stimflash, and changing the rejection threshold using "-t 5".

Photometry was done with a private IDL program, and its results were often checked against the APPHOT program in IRAF. The parameters used were an aperture radius of 3 pixels and a sky annulus of 4-8 pixels. The aperture correction was determined to be 1.47 based on a STinyTim PSF.

Results

The measured photometry can be found in the table below. Note that the measurements are made on data calibrated by dividing by a stimflash, and so the "MIPS160 Unit" refers to a ratio of the sky image to the stimflash.

Conclusions

The target was observed successfully and good S/N obtained, but the data are not yet useful for calibration due to the filter leak.
