AttributeError: 'FormatParams' object has no attribute 'per'

[sebastian-zieba]

When not fitting for period (per) and transit midtime (t0), the plotting in s30 will fail raising the following error:

t_hr = phase_hr * p.per[0] + p.t0[0] + data.toffset
AttributeError: 'FormatParams' object has no attribute 'per'

I should replace that with the following:

try:
    t_hr = phase_hr * p.per[0] + p.t0[0] + data.toffset
except AttributeError:
    # Set a custom value for 'per' attribute
    per_custom = [per_custom_value]
    t0_custom = [t0_custom_value]
    t_hr = phase_hr * per_custom[0] + t0_custom[0] + data.toffset

the per_custom_value and t0_custom_value should come for the fit_par file, as these values were set by the user and are set to be fixed if they are not free parameters.
