Hi Rod, re: > Well yes the size should be 10 lines and 36 elements but I thought you > said the SIZE was measured from the center No, I (thought I) said that the box will be centered on a point that you specify. re: > so thats why I said 5 > additional lines from the center x 18 additional elements from the > center. . Yes, the box's northern and southern edges will each be 5 pixels away from the center, and the western and eastern edges will each be 18 pixels away from the center. I just displayed the 19:55 effective radius image in a frame using: IMGDISP G13/ERAD27APR11 LAT=34 88 TIME=19:55 EU=CLW3 I took a look at the image and saw an "interesting" region whose center point is more-or-less 34:25,88:17 ("interesting" is a totally subjective observation, of course). I ran IMGPROBE specifying the center Lat,Lon for the "interesting" region as follows: IMGPROBE STAT BOX LAT=34:25 88:17 SIZE=10 36 OUTLINE=YES 6 MODE=N Name:G13/ERAD27APR11.3 Calb Pixels Minimum Maximum Mean Stn. Dev. ---- -------- ------- ------- ------- ----------- BRIT 360 193 238 220 9.060 Image Coord Earth Coord Minimum Value: 4621/13361 34:13:41/ 87:58:48 Maximum Value: 4629/13337 34:08:02/ 88:07:23 IMGPROBE: Done The result, which is attached as a GIF image, is what I think you are trying to do. Please let me know if it is not what you are trying to do. NB: my frame size is different from yours, but this has nothing to do with the statistics that were output in my example.
