Plot the ra and dec of the coordinates,
at a given epoch, scaled by their magnitude.

(This does *not* create a new empty figure.)

Parameters
----------
sizescale : (optional) float
    The marker size for scatter for a star at the magnitudelimit.
color : (optional) any valid color
    The color to plot (but there is a default for this catalog.)
**kw : dict
    Additional keywords will be passed on to plt.scatter.

Returns
-------

plotted : outputs from the plots
