CONAN._classes.load_lightcurves.transit_depth_variation
=======================================================

.. py:method:: CONAN._classes.load_lightcurves.transit_depth_variation(ddFs='n', dRpRs=(-0.5, 0, 0.5), divwhite='n', verbose=True)

   Include transit depth variation between the different filters. Note 'RpRs' must be fixed to
   a reference value in ``.planet_parameters()`` and not a jump parameter. transit depth
   variation is calculated as the deviation of each group's transit depth from the fixed `RpRs`.
   It is recommended to set ``RpRs=0``, so the deviation is actually the radius at each filter.

   :param ddFs: specify if to fit depth variation or not. default is "n"
   :type ddFs: str ("y" or "n");
   :param dRpRs: deviation of radius ratio from the reference values.
                 Must be tuple of len 2/3 specifying (mu,std) or (min,start,max)
   :type dRpRs: tuple of len 2 or 3;
   :param divwhite: flag to divide each light-curve by the white lightcurve. Default is "n"
   :type divwhite: str ("y" or "n");
   :param verbose: print output
   :type verbose: bool;
