This command does the same thing as the IP (Image Project) except that the projection is not plotted on top of the currently displayed image, but rather as a separate PLT area. This allows you examine the projection in some detail, typically by rescaling and fitting.
This command only operates on the data inside the inner boundary. These data are then projected onto the X and Y axis. For the X axis project the columns are summed, and for the Y project, the rows are summed.
The optional argument allows you to operate on the data, background, response, or data-background arrays. The default is data.
LEXTRCT> RC ! Plot the R/C projection for the data array LEXTRCT> RC S ! Plot the R/C projection for the subtracted array
