It seems there is no effect if I use
noao.twodspec
apextract
apextract.dispaxis=2
when the dispersion axis is along columns.
I am using IRAF in Ureka.
How to set the dispersion axis exactly?

apextract.dispaxis=2 is useless when the dispaxis key is 1 in the fits files, so we need to change the header first.
