A mapping for an asinh stretch, estimating the linear stretch by zscale x = asinh(Q (I - z1)/(z2 - z1))/Q Parameters ---------- image The image to analyse, or a list of 3 images to be converted to an intensity image Q : `int` The asinh softening parameter pedestal : `float` or sequence of `float`, optional The value, or array of 3 values, to subtract from the images N.b. pedestal, if not None, is removed from the images when calculating the zscale stretch, and added back into Mapping.minimum[] See also -------- AsinhMapping
