AsymmetricPercentileInterval

class astropy.visualization.AsymmetricPercentileInterval(lower_percentile=None, upper_percentile=None, n_samples=None)

Bases: BaseInterval

Interval based on a keeping a specified fraction of pixels (can be asymmetric).

Parameters:

lower_percentilepython:float or python:None

The lower percentile below which to ignore pixels. If None, then defaults to 0.

upper_percentilepython:float or python:None

n_samplespython:int, optional

Maximum number of values to use. If this is specified, and there are more values in the dataset as this, then values are randomly sampled from the array (with replacement).
