XGA v0.6.3 - Image regions bug fix

Summary

A small new release that fixes a bug in how Image class instances load regions that are assigned to them. Previously the WCS information required to ensure the regions are in the RA-Dec system was being accessed through an attribute that was only set if the image header had previously been accessed. Now the corresponding property is used, which ensures the WCS are actually loaded and not None.

XGA v0.6.0 - Significant improvements to spectral model infrastructure

Summary

This will be the final major version before the release of multi-mission XGA (which also supports eROSITA and Chandra analyses). The most significant changes have been made to the model fitting infrastructure, and it is now simple to perform (and crucially, retrieve results from) spectral fits of the same model but with different configuration and starting parameters.

The EventList class is now also capable of streaming event lists from S3 buckets, which is the first step towards the intrinsic generation of X-ray products using XGA.

XGA v0.5.1 - Revamp of entropy & mass profiles, and new thermal pressure profile

Summary

Quite a few general bug fixes, but the most important changes are to how the mass and entropy profiles work, and the introduction of a new thermal pressure profile.

Mass, entropy, and pressure profiles are no longer restricted to taking smooth models of temperature and density as their input - instead they can take data points, and interpolate between them in cases where the radial bins aren't the same. They can still use smooth models as inputs.

As a consequence of this, models for entropy, mass, and pressure have been added - these can be fit to those profiles, as they can now be purely data driven.

XGA v0.5.0 - HUGE DEPENDENCY UPDATE

Important Summary

Some bug fixes, some refinements to existing behaviour.

A pretty big new feature is that the SpecificEntropy profile class no longer behaves exactly like the HydrostaticMass profile class - in that it no longer requires you to calculate the entropy profile from fitted models to temperature and density, you can now use data points to calculate entropy as well, which is preferable. There are also models that can be fit to SpecificEntropy profiles, and you can use projected temperature profiles to calculate entropy if you wish.

The other new feature worthy of note is the addition of 'data driven' density profile calculation for galaxy clusters from surface brightness profiles. In addition to the existing 'inv_abel_fitted_model', which requires that a smooth model be fit to the surface brightness and then deprojected, you can now apply deprojection (inverse abel transforms) directly to data points - this can preserve interesting structure in the brightness profiles.

However, the biggest change is that we have finally updated all of the dependencies, and you will need to create a new environment to use this version of XGA. This was neglected for some years and it was becoming difficult to actually install XGA - that should now no longer be a problem, and if you visit the documentation site you will see instructions on how to use the newly included conda files to easily setup a compatible environment. We also aim for this to be the first release of XGA to be distributed through conda.
