v1.0 Not released on CRAN. v1.1 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. v1.2 FEATURE: Added cosmological distance calculator and a sky area calculator. v1.3 (CRAN) 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) v1.4 (not on CRAN) 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). v1.4.1 (on CRAN) FEATURE: Added radec2xy, xy2radec and getpixscale Tan-Gnomonic WCS projection solvers. FEATURE: Added cosNFWvcirc and cosNFWvesc functions to compute NFW halo unbinding. v1.4.2 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.
