120 CHAPTER 14. IMAGE ANALYSIS AND DISPLAY Export Options Spectrum Expanded view of the spectrum. raw (thin line) background (dotted line) source (thick line) Image Scaling Parameters "Hot" pixels show current Aperture Beam Selection Pixel Information CVF image (frame 12) Figure 14.3: The xcvf window.
14.2. CVF IMAGE ANALYSIS 121 The section of the GUI beneath the plotting region displays frames from the reduced CVF cube. The left-most part of this region displays astrometry information, and allows the user to select which frame to display as well the range of intensity to use. The panel at the bottom left of the display region is used to select the beam. The left panel in the display region shows the current frame in the reduced data cube. The right panel highlights the pixels currently in the aperture. In both panels, clicking mouse buttons has the following effects: mouse LEFT Selects the pixel and makes it part of the aperture. The right panel highlights the pixel. If the pixel is already selected, clicking on it has no effect. mouse RIGHT Removes the pixel from the aperture. mouse MIDDLE While held down, shows the spectrum of the current pixel in the plotting window, and the astrometry information in the bottom panel (see below). When released, the previous spectrum (if an aperture has been selected) is displayed again. The last part of the GUI displays the following information about the current pixel selected: 1. its row and column on the array 2. its intensity in the currently displayed frame 3. the equatorial co-ordinates corresponding to the pixel’s spatial location in J2000 equinox. Additional information and buttons in the last row are: 1. the ’RESET APERTURE’ button which resets the aperture and 2. the number of pixels in the current aperture. 14.2.2.2 Defining and editing apertures First, you need to the select the beam (either sky or source). The apertures are defined by pressing the LEFT mouse button on the pixel which is to be included in the aperture. Either the frame display or the aperture display windows are clickable. To remove a pixel from an aperture, position the cursor over the pixel and press the RIGHT mouse button. 14.2.2.3 Quick Look This is useful when you are curious about how the spectrum form a particular pixel looks but don’t necessarily want to include the pixel in the aperture. Position the cursor over the pixel of interest and press and hold the MIDDLE mouse button. The spectrum will remain visible while the button is held down. The astrometry information at the bottom panel is also updated. 14.2.2.4 Some miscellaneous tips 1. All messages (if any) from xcvf are displayed in your IDL session window. If you become confused, check to see if there were any messages from xcvf. 2. When using TOTAL (sum of all spectra in the aperture) to compute the current spectrum, the user should take care to use the same size aperture for both the SKY and the SOURCE beam for the sky subtraction to be meaningful. Currently, xcvf warn users if a discrepancy exists and the user tries to export the current spectrum. However, the output file will be written after the warning message is displayed.
