NUMBER: 393 MODULE: rv.fxcor SYSTEM: V2.11.1 DATE: Tue Feb 17 14:57:11 MST 1998 FROM: fitz BUG: When computing a deblended fit to the correlation peak the task may trigger a 'floating overflow' exception when quitting the deblending routine. STATUS: The bug occurs only when the velocities for each component cannot be computes and are returned as INDEF values. Starting with V2.11 the double-precision value of INDEF was changed to 10e308 and will cause an overflow when it's converted to real when saving values in the task structure. A code change is required to fix this. As a workaround be sure that all necessary keywords are in the image header prior to the correlation so velocities can be computed. A list of missing keywords is printed in the verbose output listing generated by the 'v' keystroke when the 'verbose' parameter is 'long' or 'txtonly', use the initial fit of a single function to get these keywords prior to deblending. Fixed for the next release.
