Aiapy

==================

Bug Fixes
---------

- Fixed a bug in the units on the table returned by `aiapy.calibrate.util.get_pointing_table`.
The ``X0`` and ``Y0`` columns were incorrectly being assigned units of arcseconds instead
of pixels. (`132 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/132>`__)
- Fixed an off-by-one bug in `aiapy.calibrate.update_pointing` where the
``CRPIX1`` and ``CRPIX2`` keywords were not being properly updated from the
``X0`` and ``Y0`` columns in the master pointing table. (`132 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/132>`__)

==================

Bug Fixes
---------

- Fixed a compatibility issue with sunpy>=3.1 in which creating a full-frame WCS in
`aiapy.calibrate.fetch_spikes` was throwing an exception. (`126 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/126>`__)
- Added a check on `aiapy.calibrate.update_pointing` so that passing in a submap or a map not at the
full AIA resolution, raises an exception. (`127 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/127>`__)

==================

Breaking Changes
----------------

- Pin minimum version of Python to 3.7 (`114 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/114>`__)
- Pin minimum version of sunpy to 3.0.0 LTS.

New Features
------------

- Added a new function :func:`aiapy.util.telescope_number` that returns the associated
telscope number for a given filter wavelength. (`116 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/116>`__)
- Added a new function :func:`aiapy.calibrate.util.get_error_table` to fetch and parse the
table with the associate error parameters.
This is used primarily in :func:`aiapy.calibrate.estimate_error`. (`116 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/116>`__)
- Added a new function :func:`aiapy.calibrate.estimate_error` to calculate the error for
a given set of AIA counts and the associated channel.
This is an exact port of the IDL function ``aia_bp_estimate_error``. (`116 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/116>`__)

Bug Fixes
---------

- `aiapy.calibrate.update_pointing` now skips updating keywords if the pointing values
are missing from the pointing table returned from JSOC. (`120 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/120>`__)

==================

Backwards Incompatible Changes
------------------------------

- Pin sunpy dependency to ``<=3.0`` to allow for backwards compatibility with ``search_metadata``. (`111 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/111>`__)

==================

Features
--------

- Add a flag to :func:`aiapy.psf.deconvolve` that sets negative intensity values to zero before performing the deconvolution. (`107 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/107>`__)

==================

Features
--------

- Added a function (:func:`aiapy.util.sdo_location`) to obtain the SDO location at a given time. (`57 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/57>`__)
- Added a function (:func:`aiapy.calibrate.respike`) for reinserting hot pixels into level 1 images. (`62 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/62>`__)
- Updated default calibration version to 10.
Added test for version 10 (`90 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/90>`__)

Bug Fixes
---------

- Updated default calibration version number for degradation correction.
Added tests for multiple calibration versions (`74 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/74>`__)
- Fixed a bug where an out of date calibration epoch was used if there were older duplicate versions available in the same epoch. (`90 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/90>`__)
- `aiapy.calibrate.util.get_pointing_table` now raises a more user-friendly `RuntimeError` if no pointing information can be found during the requested times.
Previously it would raise a `KeyError`. (`91 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/91>`__)
- `aiapy.calibrate.update_pointing` now searches 12 hours either side of the map date for pointing information.
This allows for some very rare instances where more than 3 hours elapses between pointing information updates. (`91 <https://gitlab.com/LMSAL_HUB/aia_hub/aiapy/-/merge_requests/91>`__)
