Version 4.2.2

Version 4.2.1

Version 4.2.0

  • Add overloads of Base's algebraic operators +, -, *, / and LinearAlgebra's dot product in Alm space; add Alm indexing functions: each_ell, each_ell_idx, each_m, each_m_idx, each_ell_m; improve almxfl!'s performance; add functions getEquatorIdx, ring2theta, getRingPixels #98, thanks to LeeoBianchi

  • Add synalm, synfast, anafast, adjoint_alm2map, adjoint_map2alm #96, thanks to LeeoBianchi

  • Add functions readClFromFITS, writeClToFITS, cl2dl, dl2cl, almxfl, almxfl!, almExplicitIndex #91, thanks to LeeoBianchi

  • Fix a bug in mollweideproj and equiproj #97

  • Fix a bug in queryDiscRing for directions close to the poles #105

  • Re-enable support for Julia 1.9 #104

Version 4.1.2

  • Use double precision in ang2pixRing and zphi2pixRing #94

  • Improve CI builds #89

Version 4.1.1

  • Bugfixes: #87

Version 4.1.0

  • New function gaussbeam #85

Version 4.0.1

  • Add checks for colatitude θ in functions that take angles as input #84

Version 4.0.0

  • Breaking change: udgrade now always assumes pess = false #72

  • Implement Base.parent for HealpixMap which returns the underlying array

  • New functions boundariesRing! and boundariesRing #81

  • New constants/functions: ORDER_MAX, nside2order, order2nside, numOfRings, ring2z, max_pixrad, queryDiscRing, queryStripRing #80

  • Use a more accurate algorithm for vec2ang [#76][#76]

  • Make NSIDE_MAX dependent on the architecture (32/64 bit) of the system #75

  • Documentation improvements #82

Version 3.0.1

  • Fix the documentation and export readPolarizedMapFromFITS #69

  • Bump dependency on Libsharp.jl to fix issue #67

Version 3.0.0

  • Breaking change: rename Map → HealpixMap, PolarizedMap → HealpixPolarizedMap, GenericMap → AbstractHealpixMap (PR#53)

  • Breaking change: Alm.alm is now enforced to be a one-dimensional array. This fixes type instability (PR#25)

  • Breaking change: Generalize the definition of HealpixMap and Alm (PR#26) so that other array types than plain Array can be used for these objects.

  • Add support for maps whose base type is Union{Nothing, T} PR#63

  • Various documentation improvements #55

  • Fix issue #61

  • Fix issue #59

  • Fix issue #57

  • Use CFITSIO.jl instead of FITSIO (PR#50, it fixes #47)

  • Add untyped constructor for PolarizedMap (PR#49)

  • Implement udgrade (PR#46, #51)

  • Implement pixwin (PR#45)

  • Implement applyFullWeights! (PR#41, #44), and #52

  • Implement ring2nest! and nest2ring! (PR#40)

  • Make ang2vec return a tuple instead of a list (PR#38)

  • Remove Manifest.toml (PR#42)

  • README has been updated (PR#39)

  • Documentation for new spherical harmonics functions has been added (PR#35).

  • Add dependency on Libsharp.jl and implement map2alm, alm2map, and alm2cl (#21, #23). Caution: this change drops support for Julia 1.0, 1.1, and 1.2, as Libsharp.jl requires Julia's artifacts, which were implemented in Julia 1.3.

  • Fix incompatibility with FITSIO 1.0 (#32)

  • Add function interpolate (#19)

  • Add functions pix2zphiRing, pix2zphiNest, ringAbove (#18)

Version 2.3.0

  • Relicense the library under GPL2 (#16)

Version 2.2.0

  • Add Appveyor support to test Healpix under Windows (#14)
  • Better structure of the code: now the source code is split into smaller files, and tests have been grouped in sets (#13)
  • New type PolarizedMap added (#13)
  • New keyword write_keywords added to saveToFITS (#13)
  • Make Map descend from the abstract type GenericMap (#12)

Version 2.1.0

  • Two new map projections: orthographic2 and gnomonic (43e90915)

Version 2.0.0

  • Use RecipesBase and Plots to display maps. The use of Plots is not mandatory and can be avoided for headless terminals.
  • Upgrade the documentation to Documenter 0.21

Version 1.1.1

  • Fix a bug in the implementation of setindex!

Version 1.1.0

  • Maps implement the iterator interface, so it is possible to treat a map like an array. This should make Healpix.jl more similar to healpy.

Version 1.0.1

  • Missing values are treated properly by project (using ismissing)
  • tod2map properly skips missing values
  • tod2map should be slightly more performant, as it uses @inbounds
  • Keyword numfmt has been added to project, equirectangular, mollweide, orthographic. The value of the keyword can be any function taking a number and returning a string; the default is x -> @sprintf("%g", x).
