Hi! In the last weeks we have finished the Astrometry linear part programming.

We added an option to solve for more pixel catalogs, which are a part of a field image. This is an important case in real world scenarios. The image below is a good illustration of this: we have a field and a lot of exposures that are used to build the final image.

Also, we are moving our code to Gnuastro, so it can be a Gnuastro program. To do this, we have to follow Gnuastro conventions, so everything can be organized. Luckily, it’s very well documented how to do it, as you can see here and also here.
