Why do all STIS filenames end with _drz.fits?
Due to an oversimplification in the shopping cart mechanism and the complexity of STIS data, which can be taken in different modes (resulting in flt, x2d, sx2, crj, etc. files), file names for STIS data added to the cart from the Inventory and Images tabs are incorrect when delivered by the shopping cart. All of the downloaded STIS file names end in _drz.fits regardless of the file extension (e.g., x2d which should end _x2d.fits). The correct filename and extension are listed in the FITS header. Note files added from the More link within the Images tab are correct. We are working on a fix for this and will update the HLA as soon as that is available.ch point, and the approximation in the search logic does not affect that case.
