GSB / Astro-Coords-0.22 / Changes 
Revision history for Astro::Coords

0.22 2024-11-01

  - Added distance method to Astro::Coords::Offset.

0.21 2023-04-17

  - Check for requests for more than 9 decimal places, which can cause an
    overflow from PAL functions.

  - Use str_ndp for Angle in_format('array').

0.20 2019-09-11

  - Units can now be given as a 2-element array such as ['hours', 'degrees'].

0.19 2018-02-07

  - Astro::Coords::Fixed::array now returns the azimuth and elevation
    in radians.

  - Changed the default number of decimal places for
    Astro::Coords::Angle::Hour to 3.

  - Updated the format specification used to parse epoch strings in
    Astro::Coords::Elements (for recent versions of Time::Piece).

  - Fixed the Astro::Coords::Angle::negate method.

  - Added warnings about the use of proper motion without parallax.
    (With Astro::PAL, significant proper motions are not applied
    unless the parallax is also given.)

0.18 2012-11-09

  - Fix inconsistency in parsing of hours vs degrees (Eric Jensen).

0.17 2012-07-16

  - Require DateTime version 0.76 to avoid problems with rise/set test scripts.

0.16 2012-07-13

  - Massive speed up in rise/set time calculation.

0.15 2012-07-05

  - Add planets() method to retrieve planet names and remove Pluto.

0.14 2012-06-04

  - Fix tests for long double Perl. Build now requires Test::Number::Delta.

0.13 2012-05-25

  - Use Astro::PAL instead of Astro::SLA. The main driver being that
    Astro::PAL can be installed from CPAN without any additional dependencies.

  - Significant speed improvements.

  - New apply_offset() method to add an Offset onto an existing coordinate
    object and return a new coordinate object.

0.12 2010-12-30

  - Update Elements interface.

  - Improve performance of DateTime usage (caching TimeZone object).

  - Support barycentric velocities.

  - Astro::Coords::Offset now has invert(), clone() and posang() methods.

  - Astro::Coords::Angle now has clone() and negate() methods.

  - Astro::Coords::Offset now allows more systems.

  - Fix problem with fractions seconds in LST calculation.

  - Fix problem with calculate() method trashing the cached DateTime.

  - Uses Module::Build.

0.10 2005-02-21

  - Major reorganization internally to use (the new) Astro::Coords::Angle
    objects for all angles. Should simplify formatting of return values.

  - datetime() method now supports DateTime objects for time
    specification. Time::Piece is now deprecated.

  - Add radial velocity support.

  - Add Doppler correction (experimental).

  - New method to obtain the native Equatorial encoding that was used.

  - set_time and rise_time now works properly for the Moon (and Sun).

  - rise_time can now be configured to return the nearest rise time
    not just the next rise_time.

  - Planet diameter is now available.

  - Galactic and ecliptic conversions now in base class (moved from Equatorial)

  - radec1950 method available.

  - Switch to GPL license.

0.07 2004-02-26

  - Add support for parallax and proper motion, epoch and equinox.

  - ra2000 and dec2000 methods always return RA/Dec J2000 for epoch 2000.0
    (equatorial only).

0.05 2003-11-17

  - Check format of input arguments (for sexagesimal parsing).

  - Add rise, set and transit time calculation.

  - Add Interpolated RA/Dec (Astro::Coords::Interpolated).

  - Add calculate method.

  - Fix orbital elements (requires recent slalib).

  - Can now ask for J2000 for all coordinate types.

  - Add name and comment method for tagging a coordinate object.

0.04 2002-08-03

  - Internal release.

0.03 2002-05-24

  - Add isObservable method.

  - Spun off Astro::Telescope into its own CPAN distribution.

0.02 2001-12-05

  - Add Astro::Coords::Calibration and Astro::Coords::Fixed.

0.01 2001-11-01

  - Initial test release to CPAN.
