Meta Index / Home Page / The task window

summary of window buttons

• Print list Prints the contents of the the drop-down list.

• Delete list Delete the contents of the drop-down list- all the sources will be deleted.

• View all Displays the whole image, with the source regions overlaid.

  Add sources Allows user to select new sources from the image by positioning the cursor over the source and clicking the left mouse-button. The process is finished when the user clicks the Finished button in the addsources dialog box window.

  Run omdetect Runs the SAS task omdetect. A dialog-box is displayed which allows the user to change some of the input parameter to omdetect. The button is disabled if the source-list is not empty- The source-list can be deleted using the Delete list button, allowing omdetect to be run.

  photometry Displays the window for performing aperture photometry on the selected source. The source photometry parameter values are displayed at the top of the window. In the middle of the window spin-boxes allow the user to change the photometry aperture radius and the inner and outer background annuli. The user can also select the background-determination method

• Select Selects the source number currently displayed in the source no spin box control for editing. A source can also be selected from the source-list displayed near the top of the screen by double-clicking on it with the left mouse button. Having selected a source, some of its parameter values will be displayed.

  Apply Recomputes the photometry for the selected source using the aperture radius and the inner and outer background annulii currently set in the spin-boxes (Aperture, BackGr r0 and BackGr r1. The computed parameters for the source will be displayed and will replace the values for that source in the source-list. Also, an average magnitude will be computed for all the magnitude determinations made by the user, plus the original one, and displayed in the combobox near the bottom of the window. Note that when a source is selected the contents of the table are erased.

  Print table Prints the contents of the logger table.

  Print averages Prints the contents of the average-magnitude table..

  Delete table Deletes the contents of the average-magnitude table.

  Delete Deletes the currently selected source from the list.

  Quit Quits the program- a new source-list file is created containing the current sources. The original source-list file is not modified.
