plot only stationary track for objects without sufficient data #9

current implementation still not working. don't know why, but setting rasbg,decbg = backtrack.radecdists(epochs2,best_pars[0],best_pars[1],0,0,0) e.g. plx, pm to zero in the radecdists function does not appear to return the proper track to plot.

to get the plot to look correct, you should set jd_tt equal to the first epoch of your data (really we should recommend or just implement this as the default). I think it looks correct for the HD 131399 A b example.
