What is the right parameter syntax for PyRAF biassec?

Question

If I use epar ccdproc in imred >> ccdred >> ccdproc, I can put [261:280,1:1032] in biassec, which is in a old iraf code by my teacher:

ccdproc @list.all o//@list.all ccdtype='' overscan+ biassec=[261:280,1:1032]

But if I use the terminal, it will say:

SyntaxError: Too many positional parameters for task ccdproc

And if I put (261:280,1:1032), (261:280;1:1032) or (261:280 1:1032), it will also pop out SyntaxError. It seems that pyraf syntax is slightly different from iraf. What is the right parameter syntax?

Answer 1

Solved, "[261:280,1:1032]".

Add quotation marks

ccdproc @list.all o//@list.all ccdtype='' overscan+ biassec="[261:280,1:1032]"
