Editing the interferometer data is not very flexible when done in the
tables. If a problem occurs, is is not easily diagnosed since
many of the parameters associated with the data acquisition are not
present: atmospheric data, total powers, ... It is however useful
when something strange occurs in the mapping process to do
plots of the input table to look for the faulty data. Using time or
scan number as X coordinate is recommended. One then may go back to
the CLIC program and flag the faulty data, tag the corresponding
scans, and keep a log of these problems so that they are not
encountered again when the
tables are reconstructed for any
reason.
Two tasks have been written that may directly edit the data in
tables:
The MAPPING program provides a more efficient, simpler and reversible interactive
tool to flag parts of a data set (command UV_FLAG).
