I have tried this script using the following:

fits_read, 'L1780_IR.fits', image_Ha,hdr
fits_read, 'L1780_Av.fits', image_Av,hdr2

HASTROM, image_Av, hdr2, image_Av_6, newhdr, hdr

writefits,'Av_6_2mass.fits',image_Av_6,newhdr

end

But it didn't do the job. Is there any other way to use the script?
I mean another calling sequence?
Thanx a lot
