GFM v6.1 release date is 2/15/2006. Spectral Line plugin beta. Engineering plugin beta. See the release notes
- The LPC update message, which appears while scans are in progress, now gives correct values rather than zeros. This value was incorrectly being reported in radians rather than arcminutes, so always appeared to have the value 0.0.
- An error that intermittently resulted in an obviously incorrect value for Tsys for beamswitched data has been fixed.
- The "L-band hysteresis" problem has been fixed. There was an inconsistency in the algorithms for antenna position interpolation and data calibration. This caused an apparent hysteresis between forward and backward scans when the scan rate was large. Note that the actual LPCs calculated (the average of the forward and backward scans) were always correct. This problem was especially noticeable at L-band during regression tests.
- Final LPC values are now calculated and displayed, even if a peak or focus scan fails the heuristics checks. Previously, the values would be reported as "unknown". Now, GFM will make its best effort to determine and display a value, even if the heuristics checks fail. Observers (if they so choose) may then ask the Operator to manually enter those values.
