Wide-field imaging #119

Open fredRos opened 6 years ago

fredRos commented 6 years ago

Currently we can have a fast result by focusing on small-field imaging. It's clearly described in the paper. But users often don't read the fine print and may get inaccurate results for wide-field images.

We can apply corrections through convolutions at some performance penalty.

This is a very good reference with algorithm discussion. https://arxiv.org/abs/0807.4161
