Hi again,

David - I'm reading data using MRDFITS - not sure I can convert the
data when reading it in??

Reimar - does it work on arrays of structures? I tried this:

IDL> x = replicate({a:0., b:0}, 5)
IDL> help, x
X STRUCT = -> <Anonymous> Array[5]
IDL> help, x, /struct
** Structure <15ee908>, 2 tags, length=8, data length=8, refs=1:
A FLOAT 0.00000
B LONG 0
IDL> y = replace_tagvalue(x, 'A', double(x.a))
IDL> help, y
Y STRUCT = -> <Anonymous> Array[1]
IDL> help, y, /struct
** Structure <15f5518>, 2 tags, length=64, data length=60, refs=1:
A DOUBLE Array[5]
B LONG Array[5]

... but it completely changed the structure.

Maybe I'll just edit the FITS file manually...
