⎛ W= ⎜ ⎝ ∑ c j 2 σ j MOPEX User’s Guide Mosaicking (mosaic.pl) 88 Mosaic Modules j ⎞ ⎟ ⎠ Equation 5.6 where σj is the pixel value of the corresponding uncertainty image, and co-added coverage C is simply the sum of the individual input coverages: ∑ C = c j j Equation 5.7 Exposure Time Weighted Average: If Integration Time Weighted Coadd is selected then MOPEX weights the co-added pixels by the exposure time given in the FITS header keyword specified. For Spitzer data, the integration time is given by the keyword EXPTIME. Sigma Weighting: This option is not recommended when sources are present. If Sigma Weighted Coadd is selected, then a co-added pixel value O is given by the following expression: O = ∑ c jI j 2 j σ j W 2 Equation 5.8 Median Mosaic: If the Create Median Mosaic box is checked then the pixels are co-added by taking the median value of the stack. Warning: Flux is not conserved. This option is useful for a quick-look mosaic, but should never be used for science. Absolute Minimum Mosaic: If the Create Absolute Minimum Mosaic box is checked in the Mosaic Settings module then the output mosaic pixel value is set to the minimum input pixel value in the stack. The corresponding uncertainty pixel is set to the value of the pixel in the interpolated uncertainty image corresponding to the interpolated image with the smallest absolute value pixel. This option is useful for outlier rejection
MOPEX User’s Guide Standard Deviation Mosaic: If the Create Standard Deviation Mosaic box is checked then a different flavor of mosaic uncertainty image is created. The pixel values S of this image are equal to the standard deviation of the interpolated image pixels in the stack: S = The variable T is the exposure time. ⎛ ⎞ 2 N∑c jTjI j − ⎜ ∑c jTjI j ⎟ j ⎝ j ⎠ N −1 5.6.20 Mosaic Modules: Mosaic Combine ( )N 2 ;N = c jTj j Command Line Equivalent: run_mosaic_combiner Default Output Directory: /Combine-mosaic De pe nds On: Mosaic CoAdder PURPOSE Mosaicking (mosaic.pl) 89 Mosaic Modules 2 ∑ Equation 5.9 This module combines the co-added tiles into a mosaicked image.
