MOPEX User’s Guide 2. Edit a previously-generated source table that was output by the Detect module, to include only those sources that you wish to extract. Note that in this case, you may find it easier to simply run APEX with Select Detect, rather than running APEX User List; 3. If you are running APEX User List Single Frame then you can use the GUI to interactively select the sources that you wish to extract. Start by selecting an input file in the Initial Setup module, open the APEX User List single frame Settings. You have the choice to either input an existing User List file, or Create User Input List. Click on the Create User Input List button, and MOPEX will bring up your input mosaic in a separate window, alongside a User Input List control window. Left-clicking on a source in the image window will add its position to the control window. Ctrl-Left click on a previously-added point source to select it without adding a second source at the same position. Shift-Left click on a source to center the image at that point. If you wish to delete a source from the input table, select it in the control window and click the “Delete Selected” button. Note that selecting a source is not the same as checking the box to the left. The checkbox simply controls whether the source is shown in the image window or not. You can also delete all sources except the ones you have selected by using the “Keep Selected” button. Once you have finished selecting your sources, press the “Save Table” button, give the file a sensible name, and then click “Save”. Click “Done” to return to the APEX User List single frame Settings window. Finally, load your newly-saved table into the User Input Fixed Positions Table File Name. 8.11 Fatal Mask Bit Patterns It is highly likely that when you reduce your Spitzer data, you will include at least one set of mask files as input into the pipeline. The pixels in the mask files all contain coded information, or "bit definitions", depending on the status of a particular pixel. For example, a pixel with bit 10 flagged in the IRAC channel 1 PMask file indicates that that particular pixel in the IRAC channel 1 array has an excessive dark current that will affect all observations, while bit 14 indicates that the pixel is dead. For a full list of bit definitions, see the IRAC and MIPS Instrument Handbooks. When running MOPEX, you need to decide which of these codes you wish to set as "fatal", i.e. which of the flagged problems you consider so bad that the corresponding pixel in your data frame should be discarded. This is done by specifying a "Fatal Mask Bit Pattern" for each mask type, in the Initial Setup module. On the command line, the Fatal Bit Patterns are set in the general settings part of the namelist. The Fatal Mask Bit Patterns are calculated as follows: Fatal Bit Pattern = 2 (value of 1st required fatal bit) + 2 (value of 2nd fatal bit) (value of nth fatal bit) + .... + 2 Basic Concepts in MOPEX 220 Fatal Mask Bit Patterns
MOPEX User’s Guide e.g. if you wished to set bits 7, 8, 9, 10 and 14 as fatal for your IRAC PMask file then you would set your PMask Fatal Mask Bit Pattern (PMask_Fatal_BitPattern in namelists) to: (2 7 + 2 8 + 2 9 + 2 10 + 2 14 ) = 18304. On the command line, you would include the following line in your namelist: PMask_Fatal_BitPattern = 18304 The Fatal Bit Patterns for the other mask files can be set in the command-line namelists with the keywords: DCE_Status_Mask_Fatal_BitPattern RMask_Fatal_BitPattern The currently recommended Fatal Mask Bit Patterns for each instrument are listed in the GUI templates.
