Released 2024-11-19
- Add more
zone_coveragetests from feedbacks from @camposandro- revert the modification introduced in v0.7.1 solving a problem but creating new ones
- improve the
zone_coveragealgorithm to 1- solve issues on very wide zones and 2- remove spurious cells when a zone vertex is on the edge of an HEALPix cell
Released 2024-11-12
- Wrong parameter (
cos(lon)instead ofcos(lat)) inh_to_h_and_shsmethod leading to possibly miss cells in cone/ring coverage in case of cones/ring much smaller than requested HEALPix cells.
Released 2024-11-08

zone_coverageno more included in the output MOC

Released 2024-07-19
- Values in
SMALLER_EDGE2OPEDGE_DIST(used inbest_starting_depth) were slightly overestimated due to a "moving" reference point for depth >= 2, see github issue #10. The error on the values should now be below the microarcsec.

Released 2022-03-22
- Method
box_coverage: relax a too restrictive constraint preventing a == b
Released 2022-01-25

cone_coverage_fullin: returns HEALPix nested cells fully covered by the given cone - Method
cone_coverage_centers: returns HEALPix nested cells having their center in the given cone - Method
ring_coverage_approx: returns HEALPix nested cells overlapped by a ring - Method
ring_coverage_approx_custom: returns HEALPix nested cells overlapped by a ring (with a custom delta depth for better precision)
Released 2020-08-05
- Add
box_coverage
- In polygon: contrary to the Java code (which was correct) a cell was added to the
moc if its 4 vertices where in the polygon (without testing possible intersection with the polygon).
This may lead to wrong coverages in the case of self-intersecting polygons
(see
nested::testok_polygone_exact_fxp). - Fix benches
Released 2020-11-02
- Default behaviour for polygons
- Add
zone_coverage. - Add

- Fix compilation warnings
- Fix clippy warnings
Released 2020-06-22.
- When Newton-Raphson method fails when looking for "special points" in polygons (due to divergence or too slow convergence) the method failed. Now returns None (i.e. no special point found).
Released 2020-05-25.
- When polygons are very large, previous code sometimes returned the complementary polygon. We now decided that for large polygons the gravity center should be inside the polygon.
Released 2020-03-04.

hash_with_dxdyalgo to be ported in glsl (WebGL) for AladinLite: is takes in input a vector (x, y, z) made of 3 single precision floats.
