        INTER-SENSITIVITY

    Compute sensitivity of an interferometer to point and extended sources.

2 FREQ$
        TASK\REAL "Frequency [GHz]"                  FREQ$

    Observed frequency.

2 BANDWIDTH$
        TASK\REAL "Bandwidth [MHz]"                  BANDWIDTH$

    Spectral resolution.

2 TSYS$
        TASK\REAL "Tsys [K]"                         TSYS$

    System temperature at the observed frequency.

2 DECORREL$
        TASK\REAL "Decorrelation coefficient"        DECORREL$

    Decorrelation coefficient (product of atmospheric and correlator quanti-
    zation decorrelation).

2 ONTIME$
        TASK\REAL "On-source integration time [hrs]" ONTIME$

    On-source integration time (you must sum-up the time spent on  all  con-
    figurations). Be careful, you must estimate and add the off-source inte-
    gration time to get the total time needed to obtain a given sensitivity.
    At Bure a large fraction of time is spent off-source for calibration.

2 NANT$
        TASK\INTE "Number of available antennas"     NANT$

    Number of available antennas in the interferometer array.

2 ANTEFF$
        TASK\REAL "Antenna efficiency [Jy/K]"        ANTEFF$

    Mean efficiency of antennas.

2 BEAM$
        TASK\REAL "Beam [arcsec]"                    BEAM$[2]

    Expected resolution of the observation (major x minor Gaussian axis).
