NUMBER: 232 MODULE: images.geomap SYSTEM: V2.9 DATE: Wed Dec 29 16:39:24 MST 1993 FROM: davis BUG: Geomap was computing an incorrect coordinate transformation if the functional form of the coordinate transformation was 'chebyshev' or 'legendre' x fit x or y order was > than 2 and the y fit was linear (x and y order equal to 2), or if the y fit x or y order was > 2 and the x fit was linear (x and y order equal to 2). This was occurring because geomap was incorrectly redefining the functional form of the linear fit to be 'polynomial'. STATUS: Fixed in 2.10.3. There is no direct workaround but setting the cross terms parameter of the linear fit to 'yes' will avoid the problem at the expense of computing one extra term in the fit.
