[AstroPy] How to change fits table header to another name

[Yannick Roehlly]

Hi Vinu,

The easiest way is to use Table:

from astropy.table import Table
t = Table.read("foo.fits")
t['RA'].name = 'RA_1'
t.write("bar.fits")

But if your FITS file has other extensions you may loose them when saving
back the table. In that case, you must use io.fits but you must know the
position of the column you want to rename:

from astropy.io import fits
hdu_list = fits.open("foo.fits")
hdu_list[1].columns[1].name = "RA_1"  # The column index starts at 0
hdu_list.writeto("bar.fits")

Regards,

Yannick
