Description

The POINT program is a pointing parameter fitting program based on the SIC user interface, and GREG for graphic display. It is called by the command:

$ POINT

A typical session with POINT is:

If some points appear discrepant in the fit or if the fit residuals are large, there are several possibilities for rejecting bad data points.

If the coverage is bad, it is interesting to fix some parameter to reduce the errors on correlated parameters. This is especially true for the radio COH, because the collimation is essentially a constant that depends only on the antenna. For example
