PRF_ResampleY_Factor = 4, Normalization_Radius = 44, MaxShift_X = 3.0, MaxShift_Y = 3.0, Angular_Distance = 6.0, Use_Photerr_for_SNR = 1, Gain_for_SNR = 1000.0, &END OUTPUT MOPEX User’s Guide Table (*_extract_raw.tbl): The preliminary extract table, which includes the fluxes and improved positions of the point sources, along with other parameters characterizing the fit. Details of the output parameters are given in the description of Select (§6.5.20). DISCUSSION Details of the fitting are given in §8.6 PRF Fitting in MOPEX. Two kinds of uncertainty estimates are output (see §8.9 Uncertainty Estimation). If the Photerr is chosen, note that the SNR value for any bad uncertainties in the box is -9.99, and these objects might be lost from the final extract table if a SNR cut "select" is done. If set, the fitting area parameters (Fitting Area X, Y) will be used instead of the output from the Fit Radius module, so make sure to unset them (leave them blank) if Fit Radius is to be used. If Fit Radius is not run, Fitting Area X, Y must be set. They must be set in APEX User List pipelines, as these pipelines do not use the Fit Radius module. APEX normalizes the PRF in the following way: if Normalization Radius (in units of PRF pixels) is set, it will normalize by the sum of the "central" PRF within that radius. By "central" we refer to the PRF corresponding to a center-of-pixel hit. If Normalization Radius is not set, APEX will normalize by the available range that the "central" PRF covers, i.e. the whole array box. Getting correct PRF-fitted absolute fluxes requires a correct PRF normalization, and possibly correction factors to take into account how your data have been calibrated. In general, it is better to keep Background_Fit turned off, as it is difficult to get a robust measure of the background within the small fitting area that is best for PRF fitting. An exception might be a very crowded field. If not used, you are relying on the results of the Extract MedFilter module to subtract the backgrounds. Point Source Extract ion (APEX) 150 APEX Modules
6.5.19 APEX Modules: Aperture Photometry Command Line Equivalent: run_aperture Default Output Directory: De pe nds On: Detect or Input user list Relevant Pipelines: All MOPEX User’s Guide Important notes: The input image for this module is not set from within the parameter block, but in the APEX Settings module, using the parameter Use Background Subtracted Image For Aperture. When using a sky annulus to subtract the background, we recommend using the original image as input rather than the background-subtracted one (i.e. do not turn on the Use Background Subtracted Image For Aperture option). PURPOSE This module calculates the flux(es) within each specified circular aperture for each source in the extract table. It will optionally subtract a background value from a user-defined annulus. The background value can be set to the median or mode of the good pixels in the annulus. The aperture photometry is calculated using an exact algorithm to compute a fractional aperture-pixel overlap. INPUT Number of Apertures: (int) Number of circular apertures to draw around each source, between 1 and 5. Aperture Radius N: (float) Radius of aperture N in pixe ls. Min Number Pixe ls: (int) Minimum number of good pixels required in the annulus. If there are fewer, it will not subtract the background. Annulus Compute Type: The method used to compute the sky background. Choices are median or mode of the good pixels in the background annulus. Inner Radius: (float) Inner radius of annulus in pixels. Outer Radius: (float) Outer radius of annulus in pixels. Use Annulus: Check this box to subtract the background as calculated using a user-defined annulus.
