I used readfits to read in data and it produced a 48 by 1221 byte array. I tried using
"ieee_to_host, data, IDLTYPE=4"
but I am having no luck converting it to a float array. Help would be appreciated !! Thanks !

I'd try this:

array = Float(data)

Cheers,

David

I tried that but it converts it to a 48 by 1221 float array and it is supposed to be a 12 by 1221 array. Any other ideas? Thank you !

Oh, I see. Try this, then:

array = Float(data, 0, 12, 1221)

Cheers,

David
