Detection (photutils.detection)#

This subpackage contains tools for detecting sources in an astronomical image.

Functions#

find_peaks(data, threshold, *[, box_size, ...])

Find local peaks in an image that are above a specified threshold value.

Classes#

DAOStarFinder(threshold, fwhm[, ratio, ...])

Detect stars in an image using the DAOFIND (Stetson 1987) algorithm.

IRAFStarFinder(threshold, fwhm[, ...])

Detect stars in an image using IRAF's "starfind" algorithm.

StarFinder(threshold, kernel[, ...])

Detect stars in an image using a user-defined kernel.

StarFinderBase()

Abstract base class for star finders.
