The function "add_observations" missing the mag_errs under Args.
Function "convert_to_array" and "compare_len" has no description.

Under: plots.py: the function "plot_lightcurve" has no description and the function should have an option to plot with errorbars in case the errors are given, and to add a binary argument True/False option to save the plot or not. The function "plot_unfolded" under "views.py" has the same issue.
