alipy's Introduction

About
=====
This is a fork of the original alipy 2 package. The main goal is to make
this code Python3 and PEP8 compliant. Other than that, it should remain 
substantially the same.

Original About
==============

This is a python package to quickly, automatically, and robustly identify 
geometrical transforms between optical astronomical images, using only field 
stars. The images can have different pixel sizes, orientations, pointings 
and filters.

alipy's Issues

Unable to match field stars of different CCDs (different pixel sizes).

I used alipy to align images of the same telescope (using the demo script) and it worked perfectly fine. But when I used the demo script to transform images of different telescopes (CCDs have different pixel sizes), it fails to find the transform. As I understand the sextractor is unable to match stars from the two images. Is there is anything that can be done to match the field stars?
