+spectra examples in hand:
+
+Keck I / HiRes : 
+     - single IRAF FITS spectra
+     - BANDIDn gives def of slice (spectrum, sigma, background, raw)
+     - WATn_001 gives units (Angstroms)     
+     - wavelength = (x-CRPIX1+1) * CD1_1 + CRVAL1
+     * how do we know the orientation?
+
+Keck I / ESI : 
+     - MEF spectra (yso/keck)
+       - spload-mef converts to a single
