Utility Functions (`photutils.utils`)
=====================================
Introduction
------------
The `photutils.utils` package contains general-purpose utility functions
that do not fit into any of the other subpackages.
Some functions and classes of note include:
* :class:`~photutils.utils.ImageDepth`: Class to calculate the limiting
flux and magnitude of an image by placing random circular apertures on
blank regions.
* :class:`~photutils.utils.ShepardIDWInterpolator`: Class to perform
inverse distance weighted (IDW) interpolation.
* :func:`~photutils.utils.calc_total_error`: Function to calculate the
total error in an image by combining a background-only error array with
the source Poisson error.
* :func:`~photutils.utils.make_random_cmap`: Function to create a
colormap consisting of random muted colors. This type of colormap is
useful for plotting segmentation images.
