Heinz, My mistake was along the lines of what you said, in the end
rtar was undefined. So that problem fixed. Now when I try to format
the file, I get this error message:
% Internal error: Attempt to store into Temp variable with dynamic
allocation..
% Execution halted at COMPARE_TARGET_OFFSET2 <C:\wave_bin\pvpro
\elam_pro/compare_target_offset2.pro( 80)> (DC_WRITE_FREE).
% Called from $MAIN$ .
Right after the loop finishes its first iteration. This is the code:
loop4:
artar=fltarr(nfiles)
axc=fltarr(nfiles)
ayc=fltarr(nfiles)
for i=0, nfiles-1 do begin
spherecenter,aimg(*,*,1),rtar,xc,yc,1,1
artar(i)=rtar
axc(i)=xc
ayc(i)=yc
status= DC_WRITE_FREE('C:\Cryo\SphereCenterData
\referencetargetdata.txt',fnames(i),artar(i),/Column, $
Dt_Template=[1], Format="(A10, 1X, F4.2)")
endfor
fnames(i): String=Array(5)
artar(i):Float=Array(5)
Thanks!
