Remove

Sources, hot spots or other features can be removed from an image using REMOVE. This can be done by:

• using the cursor to mark one or more box regions (/CURSOR)

• entering the pixels coordinates of each box (/X_MIN,/Y_MIN, etc)

• using the sources found in the previous run of DETECT.

Regions

Region selection is made using box and circle. The regions are selected using the cursor, and are by default inclusive. The /exclude qualifier will create an exclusive region. These write out a region descriptor file that has a format identical to the region descriptor file used by SAOIMAGE (which can also be used to write the region file). The region file can be used to select a part of the image for further analysis. Multiple regions can be built up, to e.g. create an annulus, or exclude part of the image. Each call to these two commands will add to the existing region file. The /new qualifier is used to start a new region selection. The region file is given by default the name of the image, with the extension .reg. Otherwise it can be specified using /regfile=.
