v0.2.6

unreleased

  • Bugfix for broadcasting operations like .+= and .=

v0.2.5

2017-11-13

  • Drop support for Julia v0.6-pre
  • Run Femtobot to fix deprecations
  • Add the OVRO-LWA sky maps to the documentation (shameless self-promotion)

v0.2.4

2017-09-15

  • Fix a bug in the Julia port of interpolation.
  • Add UNSEEN() as a sentinal value for blind or masked pixels in Healpix maps. This value is consistent with healpy and libhealpix_cxx.

v0.2.3

2017-08-26

  • Implement interpolate in Julia (fixes a bug for interpolation near phi=2pi and provides a 30% speed boost).
  • Use verify_angles in query_disc and interpolate.
  • Update to Healpix 3.31.

v0.2.2

2017-08-11

  • Implement query_disc for getting a list of all pixels interior to a disc.
  • Widen the signature of most pixel functions to Integer.
  • Fix the Mac build (cfitsio was moved away from the science tap).

v0.2.1

2017-07-09

  • The package build system has been revamped.
  • cfitsio is now correctly treated as a dependency of this package.
  • On OSX the package will install healpix and cfitsio using Homebrew.jl.
  • On Linux, we can fall back to pre-compiled shared libraries under certain conditions.
  • Pre-compiled libraries (x86_64 only) are hosted at: https://bintray.com/mweastwood/LibHealpix.jl/dependencies

v0.2.0

2017-06-18

  • Complete package re-write. The package is now compatible with Julia v0.6 only.
  • HealpixMap has been split into RingHealpixMap and NestHealpixMap. Both of these are subtypes of AbstractVector now, and nside is no longer a type parameter.
  • Alm is now a subtype of AbstractVector and lmax/mmax are no longer type parameters.
  • Indexing an Alm object by l and m now requires the @lm macro in order to play nicely with the AbstractVector interface
  • Alm and both HealpixMaps implement custom broadcasting
  • New QuantumNumberIterator that allows for easy iterating over values of l and m
  • Pixel functions that return a unit vector will now return a static 3 element array
  • Some functions that worked only with Float32 (reading/writing fits files) or Float64 (spherical harmonic transforms) now work with either.
  • Build system now uses BinDeps
  • No longer using Ptr{Void} fields because they do not play nicely with Julia's GC
  • Lots of documentation improvements
