v2.1.5

Release 2.1.5

Just to trigger building and publishing on Intel Macs.

v.2.1.4

[v2.1.4]

Minor bump to push out MAST support.

Added

• Added support for STScI MAST Tap queries.

Changed

• Updated observability example (simpler and faster).

v2.1.3

[v2.1.3]

Added

• Added support for MPC Extended Packed Provisional designations.
• Added plotting tool for annotating orbits on a fits file.

Changed

• kete.spice.get_state now accepts MPC Observatory codes as well.
• WISE SPICE kernel download location moved.

Fixed

• Plotting no longer rescales the image in place.
• Plotting now works with integer valued data.
• Plotting correctly displays the names of the coordinate frame used.

v2.1.2

[v2.1.2]

Added

• Added GAIA TAP server to kete's TAP functionality.
• Added phase correction model for comet dust.

Fixed

• Next solar noon calculation fixed to always be the future noon.

Changes

• Loading WISE FoVs optimized, at least 5x faster for already downloaded data.

v2.1.1

Small release bump to fix a bad angle calculation.

[v2.1.1]

Fixed

• Fixed the angle calculations of orbital elements in State objects where they were
  being converted to degrees twice, causing them to be multiplied by 360/2pi.

v2.1.0

[v2.1.0]

Added

• Added support for SPHEREx public data, this includes a custom constructed SPICE
  kernel.
• Added support for computing sunrise and sunset times at any location on Earth.
• Added support for approximate earth location computation, to enable precovery work
  on frames from before 1972.

Changed

• Moved name lookups for SPICE and Observatory codes to the rust backend. This speeds
  up lookup of states in python by about a factor of 2.
• Renamed wgs_84.rs to earth.rs and moved Earth related computations into it.

Fixed

• HorizonsProperties sampling and queries to horizons is more robust to unexpected
  responses from the Horizons service.

v2.0.0

[v2.0.0]

This version introduces significant rewrites to the rust core of kete.
Includes complete rewrite of the internal representation of coordinate frames, a new
internal rust class for Vectors, and how SPICE files are parsed.

Unfortunately the above changes break any binary saved files which were previously
saved by kete. Files can still be saved as binary, but the formats with the old version
are not compatible any more.

Also included in this version are quality of life changes, for example state vectors
now expose all of the underlying orbital elements directly. Queries to services such
as IRSA are now cached by default and will recover if the same query is submitted.

Added

• Added support for PTF fields of view for all public data. PTF operated from 2009 to
  2018, however data is only publicly available through early 2015.
• Generalized TAP queries to support queries to the Canadian Astronomy Data Centre
  (CADC).
• Added initial support for SPICE SCLK text kernels, allowing the conversion of
  spacecraft formatted time strings to kete.Time objects. Conversion matches cSPICE
  to near numerical precision limits.
• Added initial support for SPICE CK binary kernels, allowing conversion of instrument
  coordinate frames to equatorial frame and back.
• Exposed orbital element values on Python State objects, instead of having to convert
  the state first to an CometaryElements object.

Changed

• Saving files to any binary format will no longer be guaranteed to be compatible in
  future versions. If a file is saved by a particular version of kete, it may only be
  compatible for that version.
• Restructured frames of reference throughout the core rust code. This is a significant
  breaking change, which introduces new objects into the kete_core code. The biggest
  changes are that frames of reference are now individual classes which implement a new
  traits InertialFrame and NonInertialFrame, and removes the previous Enum for
  frames. As a result of this, there is a new class Vector<T> which has been added as
  well, which must be of type InertialFrame. Numerous places throughout the code now
  use these Vector classes, which guarantees the reference frames are preserved
  without manually performing a check for matching frames. State now use reference
  frames as well, and SimultaneousStates and FOV objects now all use
  State<Equatorial> as the base representation of the states of the objects.
• Significant rewrite of reading SPICE files, there are now wrapper view types to the
  for SPK and PCK.
• Field of Views as downloaded from IRSA are now saved as parquet files. This enables
  them to be backward compatible if there are future changes to FOV, States, or Vector
  definitions. This is a breaking change for previously downloaded FOV files, and these
  may be deleted.
• Moved plotting tools out of kete.irsa into kete.plot.
• Generalized kete.irsa tools to kete.tap, and added cached query support. Queries
  to any TAP service are now cached by default, and re-running the query will restore
  the existing results by default.
• Moved kete.mpc.table_to_states into kete.conversion.table_to_states.
• Renamed kete.wise.fetch_wise_fovs to kete.wise.fetch_fovs.
• Renamed kete.ztf.fetch_ztf_fovs to kete.ztf.fetch_fovs.
• Moved RA/DEC string parsing to rust backend.
• Many functions in python now support passing one or a list of objects, for example,
  kete.propagate_n_body can now be passed single or multiple states, and will return
  the correct type back.
• Parsing and packing of MPC Designations was re-written and moved out of Python.
• Reduced threshold for hyperbolic orbits to |ecc - 1| < 1e-4 from 1e-3.
• Improved accuracy for Apophis example by included non-gravitational forces.

Fixed

• Fixed support for MPCObservation parsing of MPC files, this regression was
  due to upstream changes at the MPC in their formats.
• Parsing some non-gravitational forces from JPL Horizons was not correctly resolving
  parameter names, this is now fixed.

v1.1.0

[v1.1.0]

Announcement: Author of Kete (Dar Dahlen) has left IPAC Caltech to begin a PhD at
TU Braunschweig in Germany. Kete has been forked from the public copy maintained by
Caltech, and future development of this fork will occur as a personal project.

Changed

• SPICE kernels were removed for the repository, and now automatically download on
  first use.
