NUMBER: 555MODULE: longslit.fitcoords
SYSTEM: V2.13-Beta[12]

BUG: If the fitting axis is 2 (the identify/reidentify features are defined by cuts along the second axis) the y coordinate for the 2D fitting will be wrong. You will notice this if data are plotted with one axis being the y coordinate. The other way you would notice this is that the transformation won't correctly remove the distortions and make a correct wavelength solution.
The only workaround is to transpose the data early before doing the feature identification and tracing. Note that you must then also reset the physical WCS after the transpose with the command "wcsreset wcs=physical".
STATUS: Fixed for the next IRAFNET V2.13 release.
