Important Notes: For use with IRAC data only. Only required if you are analyzing sources with a spectral energy distribution that is "blue", that is, falling with wavelength through the IRAC passbands.
PURPOSE
Creates the Array Location-Dependent Correction frames for each of the BCD files used in making the mosaic.
INPUT
You must specify an Array Location-Dependent Correction file (Array Correction Frame) and a Pixel Area distortion file (PixArea Frame ) in the Mosaic Settings module.
COMMAND LINE INPUT
See next section.
OUTPUT
Array Correction frames (corr_*.fits): The Array Correction frames corresponding to the BCDs. They are written to the Array_Corr_Data output directory.
DISCUSSION
For use with IRAC data only. This module creates the Array Location-Dependent Correction frames for each of the input BCDs to allow users to correct their photometry when observing blue sources on the final mosaic. In this case, “blue” means anything with a spectral energy distribution that is falling through the IRAC passbands and, in practice, includes most galactic and many extragalactic sources. For more information on the array location-dependent correction, and how to apply it to your photometry, see the IRAC Instrument Handbook. This is not an issue with MIPS data.
