What's New

0.2.1 (18 Apr 2026)

  • Added support for astropy==7.2.0 sky coordinates.

By Callan Gray.

0.2.0 (31 Mar 2026)

  • Added {py:mod}coordinates submodule with {py:func}coordinates.dataset_to_skycoord and {py:func}coordinates.skycoord_to_dataset explicit conversion functions for working with {py:class}astropy.coordinates.SkyCoord.

  • Added support for specialized quantities:

    • {py:class}astropy.time.Time
    • {py:class}astropy.time.TimeDelta
    • {py:class}astropy.coordinates.Angle
    • {py:class}astropy.coordinates.Longitude
    • {py:class}astropy.coordinates.Latitude
    • {py:class}astropy.coordinates.Distance
    • {py:class}astropy.units.LogQuantity

  • Added {py:meth}Dataset.astropy.to_skycoord accessor.

By Callan Gray.

0.1.0 (17 Jul 2025)

  • Added equivalencies parameter to {py:meth}DataArray.astropy.to and {py:meth}Dataset.astropy.to.

  • Removed registry parameter from {py:meth}DataArray.astropy.quantify and {py:meth}Dataset.astropy.quantify.

  • Migrated pint.Quantity usage to {py:class}astropy.units.Quantity, pint.UnitRegistry to {py:mod}astropy.units, pint.UnitRegistry.formatter to {py:mod}astropy.units.format ({pull}1)

    Notable behavioural differences include:

    • Unit registry instance is managed at module scope instead of local scope.
    • Multiplying by an array by an {py:class}astropy.units.Unit coerses to {py:class}astropy.units.Quantity of float64. Explicit construction required to use other numpy dtypes.
    • {py:class}astropy.units.Quantity uses unit and value members instead of units and magnitude.
    • Unit() is not an instance of {py:class}astropy.units.Unit, only {py:class}astropy.units.UnitBase.
    • Different format literals, see built-in formats.
