MOPEX User’s Guide Use Standard Deviation to Detect: If checked, the standard deviation mosaic is used as the uncertainty estimate in image segmentation. Use Uncertainty to Detect: If checked, the uncertainty mosaic is used as the uncertainty estimate in image segmentation. Sigma Weighted Coadd: If checked, the input uncertainties will be used as weights by the Mosaic CoAdder module. Use Refined Pointing: Check this to use the alternate FITS pointing keywords created by the offline pointing refinement script (pointing_refine.pl). Do not switch this on unless you have manually run pointing refinement outside of the normal BCD pipeline products. Most users will never use this option, as pointing refinement is not recommended for Spitzer data. If you believe that there is a problem with the pointing of your data with respect to e.g. the 2MASS catalog, please email the Spitzer Helpdesk for assistance. Use Bright Object Mask: Select this option to use the object mask generated by the Bright Detect module in the full image segmentation. COMMAND LINE INPUT The following parameters are set in the Global Parameters part of the namelist. Note that if both MOSAIC_PIXEL_SIZE_X(Y) and MOSAIC_PIXEL_RATIO_X(Y) are both set, the former takes precedence and will override the latter.

INPUT User Input Fixed Positions Table File Name: (User List only) The input file containing the list of user-specified positions for source extraction. See §8.10 for more information. Use Input List Type: (User List only) The type of positional input listed in the User Input Fixed Positions Table File. Options are 0 - positions in [x,y] (pixe ls); 1 - positions in [RA,Dec] (degrees) or 3 - positions in both [x,y] & [RA,Dec]. Point Source Extraction (APEX) 111 APEX Modules
