Dome flat does a better job e.g. 9749 after sky subtraction fringes look better. (didn't change elevation for this one) For 974, had to change elevation - dome flat is still a bit better than internam one but not much. Look at final extracted spectra Keep everything for now. Final extracted spectra dont show much difference. Use dome flats where we have them but internal ones OK.
