**Test 5: IRAF test **

Step 1) rfits image.fits to image.imh if using IRAF 2.10 or earlier:

[But why? You should be using 2.11.1 by now. Get with it!]


Step 2) Then cut and paste the following, whilest timing:

rotate input=image outp=temp1 rotat=45
rotate input=temp1 outp=temp2 rotat=45
rotate input=temp2 outp=temp3 rotat=45
rotate input=temp3 outp=temp4 rotat=45
rotate input=temp4 outp=temp5 rotat=45
rotate input=temp5 outp=temp6 rotat=45
rotate input=temp6 outp=temp7 rotat=45
rotate input=temp7 outp=temp8 rotat=45


Step 3) Then imcombine temp*.imh while timing.
