frame column or row.  Download cursor column and row are intended to be useful only when the 

cursor is set to follow the centroid, or peak location. 

The following describes how to set the pan window to the lower right corner of  the detector.  In 

this example the lower right corner of the detector is at (744, 512).  The frame data size is 32 X 

30.  The capture resolution value is 2, so we must multiply the data size by 2

2

=4.  Therefore the 

actual size of the capture window is 128 X 120.  To put the capture window in the lower right 

corner we subtract the capture window size from the lower right limits, 744-128=616 and 512-

120=392.

Frame coordinates are used for the frame data stored in the frame buffer.   Frame coordinates are 

dependent only on the frame size.  Frame coordinates are always positive with the origin in the upper 

left corner.  Frame coordinates are specified with column and row values.  Column values increase to 

the right and are numbered from 1 to the frame width.  Row values increase going down and are 

numbered from 1 to the frame height. 
Frame coordinates are used in the :RCC? and :RCR? commands to specify which column and row to 

download. 
Although :RCC? and :RCR? allow you to download data from the current cursor column and row, there 

is no way to associate the cursor location in world coordinates (described below) with a particular data
