Hi,
Assuming you want to build a mosaic of all these small images... I think you
could start with the following. Depending upon how X and Y are defined, you may
need to fiddle with the coordinates in arr[X[i], Y[i]] within the loop.
minX = MIN(X, max = maxX)
minY = MIN(Y, max = maxY)
w = maxX + 7
h = maxY + 7
arr = BYTARR(w,h)
For i = 0L, nSubImages-1 do $
arr[X[i], Y[i]] = SubImage[i]

Ben,
Multiple attempts were made with like success.
For clarification:
Each Cent(X,Y) corresponding subimage of 7x7. Ultimately I would
like to take the Center of Mass for each 7x7 and plot with
corresponding Cent(X,Y) to create a larger plot. This will provide
how the Center of Mass changes for each Cent(X,Y) position.
Cent(X, Y)
127.587 113.962
127.349 114.008
127.163 113.999
127.046 114.055
Subimage correspond to index
