def plotsrcazel(planet='', srcfile='', date='', obs='ALMA', plotsun=False, plottype='', saveplot='', elimit='3.0deg'):

    '''

    plot Azimuth/elevation track of a source (or list of sources)

    on given date. For solar system objects known to Measures(this excludes minor planets, Jovian moons, etc), 

    name is sufficient but for other sources

    RAs and Decs are required. 

     (requires getazel.py)

    Input:

    planet - a planet (optional)

    srcfile - (optional) An ascii file with source_name coordinates (J2000) seperated by

              a white space. A line with '#' will be skipped.

              The solar system can also be include without coodinates.

    date - 'YYYY/MM/DD' if not specified it will be prompted to enter later

    obs  - observatory name (ALMA,EVLA,etc)

    plotsun - True will plot the Sun also

    plottype - Az, El, or both (if left blank it will ask to enter later)

    saveplot - save to the plot to ps file with the name specified in this paramter

    elimit - draw horizontal line to indicate elevation limit.

    Examples:

        plotsrcazel('Uranus')  # enter date, plottype when prompted

        plotsrcazel(planet='Uranus', date='2012/06/01', plottype='both') 

        plotsrcazel(planet='Uranus', srcfile='calandtarget.txt')    #plot Uranus and sources defined
