def solar_system_setjy.brightness_Mars_int	(	MJDs,
		frequencies
	)

Planck brightness for Mars.  this one is different because
the model is tabulated vs. frequency *and* time.
inputs:
    MJDs = list of MJD times
    frequencies = list of [start, stop] frequencies for
                which to calculate the integrated model.
                example: [ [ 224.234567e9, 224.236567e9 ] ]

def solar_system_setjy.brightness_planet_int	(	source_name,
		frequency
	)

brightness temperature for supported planets.  integrates over
a tabulated model.  inputs:
    source_name = source name string
    frequency = list of [start, stop] frequencies for
                which to calculate the integrated model.
                example: [ 224.234567e9, 224.236567e9 ]

def solar_system_setjy.solar_system_fd	(	source_name,
		MJDs,
		frequencies,
		observatory,
		casalog = `None`
	)

find flux density for solar system bodies:
    Venus - Butler et al. 2001
    Mars - Butler et al. 2012
    Jupiter - Orton et al. 2012
    Uranus - Orton & Hofstadter 2012 (modified ESA4)
    Neptune - Orton & Hofstadter 2012 (modified ESA3)
    Io - Butler et al. 2012
    Europa - Butler et al. 2012
    Ganymede - Butler et al. 2012
    Titan - Gurwell et al. 2012
    Callisto - Butler et al. 2012
    Ceres - Keihm et al. 2012
    Juno - ?
    Pallas - Keihm et al. 2012
    Vesta - Keihm et al. 2012
    Hygeia - Keihm et al. 2012

inputs:
    source_name = source name string.  example: "Venus"
    MJDs = list of MJD times (day + fraction).  example:
           [ 56018.232, 56018.273 ]
           must be sorted in ascending order.
    frequencies = list of [start, stop] frequencies for
                  which to calculate the integrated model.
                  example:
                  [ [ 224.234567e9, 224.236567e9 ],
                    [ 224.236567e9, 224.238567e9 ] ]
    observatory = observatory name string.  example: "ALMA"

returned is a list, first element is the return status:
    0 -> success
    1 -> Error: unsupported body
    2 -> Error: unsupported frequency or time for body
    3 -> Error: Tb model file not found
    4 -> Error: ephemeris table not found, or time out of range
         (note - the case where the MJD times span two ephemeris
          files is not supported)
    5 -> Error: unknown observatory
second element is a list of flux densities, one per time and
    frequency range, frequency changes fastest.
third element is list of uncertainties (if known; 0 if unknown),
    one per time and frequency range, frequency changes fastest.
fourth element is a list of major axis, minor axis, and PAs in
    asec and deg, one per MJD time.
fifth element is a list of CASA directions, one per MJD time.
