disptrans : Image header parameter not found (EXTVE
Paula R. T. Coelho wrote on May 08, 2006
hello,
i'm trying to use disptrans to transform an SDSS spectrum from vaccum to air wavelength but i get
onedspec> disptrans sloanstar1 sloanstar1air angstroms air=vac2air
Warning: Image header parameter not found (EXTVER)
I read in another forum here that this message can be hiding another error, then i tried adding the keywork
onedspec> hedit sloanstar1.fits EXTVER 1. add=yes
add sloanstar1.fits,EXTVER = 1.
update sloanstar1.fits ? (yes):
sloanstar1.fits updated
But i keep getting the EXTVER not found message.
any idea how can i get to the source of the problem? i'm putting below the image header.
thx a lot
paula

hello there,
i've actually found it. the sloan spectrum is not 1D, so i had to apply the task as
disptrans sloanstar1[0][*,1] sloanstar1air angstroms air=vac2air
