In DLSP, they approximately ; cover one fringe wavelength (perhaps a little more) and range over the weak ; lines to the red of 6302.5 in order to start and end in the continuum. ; These are given in terms of spectral pixel index of the merged images after ; removal of spectrum curvature. crw1 = 6 & crw2 = 12
