PERSON RESPONSIBLE

DESCRIPTION

SMASFREQ re-labels frequencies for each of spectral windows using the follwoing recipe: sfreq(i) = sfreq(i) + 0.5*sdf(i) for i =1,2,5,6,9,10,13,14,17,18,21,22 sfreq(i) = sfreq(i) - 0.5*sdf(i) for i =3,4,7,8,11,12,15,16,19,20,23,24 sfreq(i) must be the original sky frequency from the raw SMA data; sdf(i) must be the original frequency channel increment from the raw SMA
         data.   

The output contains the corrected sky frequency label and all other data from the input file.
