plot_mica_constraints

macro_lightning.plot.plot_mica_constraints(points: Union[None, Sequence] = None, label: bool = False)[source]

Plot Constraints from Mica.

A longstanding constraint comes from examination of a slab of ancient mica for tracks that would have been left by the passage of a macro moving at the typical speed of dark matter in the Galaxy. This was used to rule out macros of \(M_x \leq 55\,\) g for a wide range of cross sections [1], [2], [3]

Parameters
pointsndarray, optional

N x 2 array for a Polygon if None (default) will load from load_mica_constraints()

Returns
Polygon
Other Parameters
labelbool

whether to add the label ‘Mica’
