List of centroid software

from email to astropy list (subject: got centroid?; author: wkerzendorf@gmail.com):

--- Adrian Price-Whelan adrianmpw@gmail.com -- `import scipy.ndimage as snd

labels, num = snd.label(imageData > (2.*sigma), np.ones((3,3)))

starCoordinates = snd.center_of_mass(imageData, labels, range(1,num+1))`

--- Marshall Perrin mperrin@stsci.edu --- You can get the entire webbpsf package from http://www.stsci.edu/jwst/software/webbpsf, but as that's overkill for this purpose I attach here just the one relevant file.

--- Russell Owen rowen@uw.edu ---

One option is PyGuide: http://www.astro.washington.edu/users/rowen/PyGuide/Manual.html
