Meta Index / Home Page / The spectrum-selection window

Summary of the buttons

• Cancel Returns to the main window and any operations that have been performed (such as selecting or deleting a spectrum) are ignored.
• OK If any spectrum regions have been selected the regions are processed and added to the current list of spectral regions.

  Delete The list of newly selected spectra is deleted and the image is redrawn- minus the these extraction regions. Note that any spectra that existed at the start of the selection session will not be deleted- see main Main window buttons if you wish to delete every spectrum

• Image Allows the user to change the image appearance using ds9 (the only parameters that can be changed are color and scale).

• Information Allows the user to display information about either the program, exposure or image details. On clicking this button, a menu appears and the user should click the relevant menu button.

  x First-order If this button is ``checked'' then the program will refine the position of the cursor x-position by computing the centroided x position of the first-order source.

  yZero-order If this button is ``checked'' then the program will refine the position of the cursor y-position by computing the centroided y position of the zeroth-order source.

• Parameters Allows the user to change the input parameters to omgrism or omgrismplot.
