Identify geometrical transformations between optical astronomical images

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. For the documentation, please refer to the original page: http://obswww.unige.ch/~tewes/alipy/ 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. http://obswww.unige.ch/~tewes/ Installation ============ Quick : python setup.py install To create a source distribution : python setup.py sdist More info : http://docs.python.org/distutils/ To generate the documentation ============================= cd doc make apidoc make html --> _build/index.html
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?
Hi,
Thank you for share the code, it has been very helpfull to our astronomy project.
I found a small bugfix on alipy/align.py:208
The parameter 'b' must be removed in order to exec with python3.
Take a look on https://stackoverflow.com/questions/34283178/typeerror-a-bytes-like-object-is-required-not-str-in-python-and-csv
I could make a pull request if you prefer, but you should give me permissions.
Thank you.
