Abstract

This is the routine 70µm flux calibration with a stellar source. The target was HD 163588. The data were obtained as expected, and the calibration factor for this campaign is 1.54±0.11×10⁴ µJy/arcsec²/MIPS₇₀Unit.

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 this campaign, and specifying the 70µm parameter file. The data were combined using a custom IDL routine which includes the following steps:

Throw out the first DCE after each stim DCE to reduce the effect of the stim latent.
Measure the median background level in the good part of side A, and subtract it from the whole image (this is a simplified way of removing the stim latent from the image).
Apply integer pixel shifts (determined using the WCS) to align the images.
Apply sigma-clipping (typically 3 sigma) and average the remaining pixels.

Photometry was performed on the mosaicked images with a custom 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. Sky values that deviated by more than 3 sigma from the median were rejected. The aperture correction was determined to be 1.27 based on a STinyTim PSF. Noise measurements include only the standard deviation of the pixels in the sky annulus.

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 "MIPS₇₀ Unit" refers to a ratio of the sky image to the stimflash. Due to the median-subtraction process described above, the residual background should be close to 0, which accounts for the small value of and large error on the background measurements in the table. The final calibration factor quoted in the abstract is the average of the two measurements in the table, which were converted to surface brightness using a pixel size of 9.89 arcsec.
