SYSTEM: V2.10.0 - V2.10.2
NUMBER: 251 MODULE: sarith, scopy SYSTEM: V2.10.0 - V2.10.2 DATE: Wed Jun 29 17:32:20 MST 1994 FROM: valdes BUG: For multispec spectra which have a doppler factor in the coordinate system description (a non-zero value for the 7th field following the number of pixels) making a copy or doing arithmetic will cause the wavelength zero point to be off by a factor of 1/(1-z*z). The workarounds are to either avoid introducing a doppler factor, accounting for the error, or explicitly setting w1,w2 (but note bug #214). STATUS: Fixed 10/92 and included in V2.11.
