celestial 1.4.6 (2018-11-29)

FEATURE: Added Planck 2018

FEATURE: Added car2sph directly (reduce dependencies

FEATURE: Some speed things for coordmatch (smallapprox

celestial 1.4.2

FEATURE: Now also support Sine-Orthographic projections and can detect the header CTYPE

FEATURE: Added internalclean function that cleans up a single table that has duplicate (N>1 within some sky position tolerance) sources

celestial 1.4.1 (2017-08-24)

FEATURE: Added radec2xy, xy2radec and getpixscale Tan-Gnomonic WCS projection solvers

FEATURE: Added cosNFWvcirc and cosNFWvesc functions to compute NFW halo unbinding

celestial 1.4

CHANGE: cosdistAngSize is now more accurately named cosdistAngScale

FEATURE: Added NEW cosdistAngSize and cosdistAngArea functions that conpute angular properties of extended sources (e.g. galaxies or halos

FEATURE: Added cosvararea function, which is a simpler interface to cosvarsph where the assumption is aside=bside

FEATURE: Added cosgrowRhoMean function, which is the mean matter density as a given redshift

FEATURE: Added NFW profile stuff

FIXED: cosgrow RhoCrit column had a bug that meant it scaled by H(z) not H(z)^2 (cosgrowRhoCrit had no bug

FEATURE: Added various Planck related functions (cosplanck

DOCS: Fixed a couple of document issues

FEATURE: Added Planck 2015 cosmology to cosref

FEATURE: Added cosdistCoDist12ang function (and related) for arbitrary comoving separations

FEATURE: Added Duffy 2008 mass to concentration relation

FEATURE: Added Driver & Robotham 2010 cosmic variance calculator

FEATURE: Added cosgrowDeltaVir to find over density compared to critical to Rho_crit from Bryan & Norman (1998

FEATURE: Added coshaloSigmaToTvir (virial temperature of halo/gas

FEATURE: Added cosgrowCoVel (cosmological recession velocity

FEATURE: Added cosgrowPecVel (peculiar velocity

DOCS: New cosdist examples by John Peacock (discussed when visiting ASGR at ICRAR in 2016

celestial 1.3 (2015-06-10)

FEATURE: Added individual cosmology routines as separate functions

FEATURE: Added new cosgrow (structure growth) and cosmap (generic parameter inputs, not just redshift) functions

FEATURE: Added sky coordinate matching functionality (coordmatch

celestial 1.2 (2015-01-10)

FEATURE: Added cosmological distance calculator and a sky area calculator

celestial 1.1 (2013-08-10)

FEATURE: Added support for many more ways of specifying deg2dms outputs, e.g. 2d34m45.5s and 2:34:45.5. Code can also take string versions of HMS and DMS coordinates and convert them back to degrees
