The Undo option returns the image to the value it contained immediately prior the current image.
The BlackTape option invokes an interactive controller that allows the user to define and byte-fill arbitrary regions of the image.
The Fill Zeros option invokes window that attempts to detect missing data (represented by blocks of row-oriented values below some threshold limit) and fill it in via interpolation.
The Flat Field option applies the flat-field filter to compensate for hardware dependent variances in the image.
The Histogram Equalize option histogram equalizes the image.
The Median option applies the IDL built-in MEDIAN procedure to the image with a 7x7 mask size.
The Scale Intensity option invokes a dialog window that scales the intensity of the image beginning from a specified offset.
The Smooth option applies a smoothing filter. The smoothing function is defined as
The Solar Zenith option computes solar zenith angles for every pixel of the image and invokes a dialog to control region selection and pixel filling options.
The Subtract Cosmic Ray option invokes a dialog window to either automatically or interactively reduce the effects of cosmic rays within the image.
The Subtract Dayglow subtracts the effects of dayglow.
The Subract Horizontal Lines option applies a filter that eliminates spacecraft level defects in data transmission. These defects appear as black horizontal lines in the image.
The Subtract Slope option compensates for the drift of an image as a scan lines are obtained from the CCD.
