+ COSMIC RAY DETECTION AND REPLACEMENT
+
+
+INTERACTIVE IMAGE CURSOR COMMANDS
+
+When using the image display cursor to define a list of training objects
+the following keystrokes may be given.
+
+? Help
+c Identify the object as a cosmic ray
+s Identify the object as a star
+g Switch to the graphics plot
+q Quit and continue with the cleaning
+
+There are no colon commands.
+
+
+INTERACTIVE GRAPHICS CURSOR COMMANDS
+
+ The graph shows the ratio of the mean background subtracted flux within the
+detection window (excluding the candidate cosmic ray and the second brightest
+pixel) to the flux of the candidate cosmic ray pixel as a function of the
+mean flux. Both coordinates have been multiplied by 100 so the ratio is in
+precent. The peaks of extended objects have high flux ratios while true
+cosmic rays have low ratios. The main purpose of this step is to set the
+flux ratio threshold for discriminating stars and galaxies. The cursor
+keys are:
+
+? Help
+a Toggle between showing all objects and only the training objects
+d Mark candidate for replacement (applys to '+' points)
+e Mark candidates in a region for replacement (applys to '+' points)
+q Quit. Returns to training or to replace the selected pixels
+r Redraw the graph
+s Make a surface plot for the candidate nearest the cursor
+t Set the flux ratio threshold at the y cursor position
+u Mark candidate to not be replaced (applys to 'x' points)
+v Mark candidates in a region to not be replaced (applys to 'x' points)
+w Adjust the graph window (see GTOOLS)
+<space> Print the pixel coordinates for a candidate
+
+There are no colon commands except those for the windowing options (type
+:\help or see GTOOLS).
