Hi
I'm looking to get rid of the for loops below.
They make two arrays;
one containing evey second column and evey second row
the other containing evey second column and evey alternate row

;----------------------------------------------------------- -------------------------------------------------
x_data = 3072
y_data = 512
DATA_size = [x_data/2,y_data]
Data_sets_ev = bytarr(DATA_size[0],DATA_size[1])
Data_sets_od = bytarr(DATA_size[0],DATA_size[1])

for i = 0, (DATA_size[0]/2)-1 do begin
for j = 0, DATA_size[1]-1 do begin
Data_sets_ev[i,j] = my_data[(2*i),(2*j)]
Data_sets_od[i,j] = my_data[(2*i),(2*j+1)]
endfor
endfor
;----------------------------------------------------------- -------------------------------------------------

This is to extract a couple of NOAA14 AVHRR Sea Surface Temperature
measurements. The different spectral bands overlap in the data file,
hence they need to be separated by the above.

Thanks
