efcal (you may have to type ~jball/bin/efcal at the Fourier
prompt)
When it opens you will see this:
efcal calculates flux and efficiency from planets
Year and day-of-year are 2006 60, change to
type in the day number when you observed in the form shown. You
will then need to type in the frequency (IN MHz). Then the screen will look
like this:
Frequency is 43122.000 MHz, change to
Wavelength is 6.95 mm
Antenna beamwidth is 47.0 arcseconds
1 Mercury
2 Venus
4 Mars
5 Jupiter
6 Saturn
7 Uranus
Pick a planet number:
Select the number of the planet you observed (Example Mars = 4)
If you pick Mars, you will see the following table:
Pick a planet number: 4
Brightness temperature of Mars is 202.0 K
Distance to Mars is 1.3458 AUs
Semi-diameter of Mars is 3.47 arcseconds
True flux of Mars is 10.3 Janskys
Beam-filling correction is 1.0076
Corrected flux is 10.2 Janskys
If you have an antenna temperature, then I can
calculate aperture efficiency, but I do not do
gain or atmospheric-attenuation corrections.
Type (corrected) antenna temperature:
Type in the Antenna temp from the DSS table at the prompt
and the result will be the Antenna Aperture efficiency.
The number YOU are most interested in is the Corrected Flux (in the
above case it is 10.2 Janskys
If the antenna temp from the DSS is 1 K, then the antenna will be
reporting a line strength of ~10 J / degree K
