…lass) - the `get_section` method in now an empty method from `BaseWindow` class and is properly implemented for inherited class - when adding window with `add_ell_cl` the duplication of windows with corresponding window indices is also done for TopHatWindow and its inherited class such as `LogTopHatWindow`

I think this will crash if window.min is an integer?

True, we must ensure window.min is an array. This will fail here but also here.
The min/max class attributes must be arrays. We can use np.asarray within the __init__ of TopHatWindow but I think this is related to the redesign/rethink of the window classes you mention.

Following discussion #81 , this PR proposes to extend the ability to get window for
(Log)TopHatWindowthe same asBandpowerWindow.When filling data via
add_ell_clfunction, the(Log)TopHatWindowobject is associated to awindow_indtag which indexes its position related to data index.When retrieving the windows via
get_bandpower_windows(it may be worth renaming this function intoget_windowssince it is not anymore dedicated to onlyBandpowerWindow), then the full binning array is computed given the selected indices (here again, in the same way asBandpowerWindow).The important thing to think about is that
(Log)TopHatWindowobject is now storing the whole bin edges and not a pair of min/max value. Nevertheless, it should be backward compatible since min/max scalar values can also be represented by one entry array.We may understand this feature is not required or desired and that it exists other way to extract the windows (using
get_tagfunctions for instance, see #81 discussion) but the important point is that it allows to treatBandpowerWindowand(Log)TopHatWindowobjects the same way without assuming or accessing the type of window.This will close #81
