The integration time (INT_TIME) is defined as the length of time over
which the data were averaged to yield the given data point. For large
sources, e.g. wide binaries, long integration times can significantly
lower the averaged fringe contrasts. Taking the system variable !int_time
to specify an upper limit for the integration time in seconds which will
not require integrating the model visibilities,
will compare the
actual integration times to this limit and determine the maximum number
of computations required to cover the largest integration interval. The
step size for each observation will be adjusted according to the actual
integration time of the particular observation, given the number of
computations.
