toasty 0.19.1

toasty 0.19.1 (2024-07-21)

• Update for Numpy 2.0 compatibility (#102, @pkgw). Previous releases will
  work in most cases, but are not 100% compatible.
• If guessing parallelism in a Slurm HPC execution environment, try to respect
  the job's resource allocation (#101, @pkgw). Often, on an HPC cluster the
  number of CPU cores on the host machine will be a bad indicator of the
  parallelism level that you should target, because you may only be allocated a
  small fraction of them.

toasty 0.19.0

toasty 0.19.0 (2023-12-14)

• Implement a --tiling-method argument for toasty view (#97, @pkgw). This
  allows you to force the choice of a specific method. In particular, sometimes
  it is helpful to force the use of TOAST to get the most accurate display over
  large angular sizes.
• Fix an outdated usage that broke processing of all-sky plate carrée ecliptic
  images with Astropy 6.x (#99, @pkgw)
• Fix TOASTing of multi-plane (e.g, RGB) images that don't cover the whole sky
  (#99, @pkgw). This fixes processing of RGB images that have lots of pixels but
  don't necessarily cover huge solid angles.
• In toasty tile-study, if we're getting WCS information from a FITS file but
  its dimensions disagree with the input image, try rescaling the pixel size if
  the overall image shape is the same (#99, @pkgw). This reproduces behavior
  already implemented for AVM processing, and helps if, say, you want to process
  a large image where you've submitted a scaled-down version of it to
  Astrometry.Net.
• Various fixes to the test suite and CI system.

• Fix tiling on macOS+Py3.7 due to an unexpectedly unimplemented API (#94,
  @pkgw).

The DOI of this release is 10.5281/zenodo.7058238.

toasty 0.18.0

toasty 0.18.0 (2022-09-06)

This release of Toasty contains a whole boatload of improvements! There are
no less than three major ones:

• Support tiling FITS data to the all-sky TOAST projection (#86, @imbasimba)!
  Now you can create all-sky FITS datasets that can be displayed in the latest
  release of the WWT engine. This includes a new routine to automatically
  determine the appropriate TOAST resolution level.
• A new -t option to toasty view allows you to view FITS data on remote
  systems using SSH tunneling (#87, @pkgw)! The tunnel mode uses SSH to tile
  the data on the remote machine, run a server, and tunnel the server to the
  local machine for display by your web browser.
• Finally, Toasty releases are now automatically deposited with Zenodo and
  assigned DOIs in the process. This makes it possible to cite the Toasty
  software, indicating exactly which version you were using, in scholarly
  context. The new command toasty show version-doi will display the DOI of the
  specific version of Toasty that you're running.

Some smaller improvements support these changes:

• Some of Toasty's internal systems were reorganized to allow for more efficient
  and flexible processing of pyramids (#89, #90, @pkgw). It is now possible to
  perform the "cascade" operation on sub-pyramids of data, allowing for parallel
  processing in HPC scenarios. A new toasty.pyramid.Pyramid data structure
  consolidates related code, reducing several nearly duplicate algorithms, and
  provides a more coherent formalism for treating operations on pyramids.
• Also, the code for filtering TOAST pyramids based on latitude/longitude bounds
  was fixed to work when the in-bounds area spanned more than 180 degrees, and
  also was made faster using Cython.
• Other efficiency improvements include:
  • Not writing all-flagged images (#88, @pkgw)
  • Avoiding creation of pyramid directories when reading imagery
  • Avoiding launching parallel operations when there is no work to do
  • Consolidating preparatory work for parallelized cascading
• When Toasty operations are being run in non-interactive scenarios, progress
  bars are now printed much more rarely and without screen overwrites, making
  for smaller and more readable log files (#88, @pkgw). This functionality is
  provided by a small new toasty.progress module.
• 16-bit integer images are now supported (#84, @imbasimba).
• DASCH FITS files with TPV distortions are now loaded with the correct LONPOLE
  setting.

The DOI of this release is 10.5281/zenodo.7055477.

toasty 0.17.1

toasty 0.17.1 (2022-07-14)

• Properly match and propagate diagonal PC headers in multi-tan processing (#83,
  @pkgw). This fixes processing of the JWST Level 3 FITS data for the deep
  field, which are on a rotated TAN projection.

toasty 0.17.0

toasty 0.17.0 (2022-07-12)

• Add an --avm-from option to toasty tile-study, which would have been
  useful with the JWST imagery released yesterday (#82, @pkgw).
• Support tiled FITS in toasty tile-healpix (#79, #80, @pkgw), and add a
  --force-galactic option.
• Avoid HEALPix HDUs without data (#79, @pkgw)
• Add some diagnostics for spatial AVM information in toasty check-avm (#78,
  @pkgw)
• Update tests for new wwt_data_formats constellation support and other
  changing dependencies.

toasty 0.16.1

toasty 0.16.1 (2022-01-27)

• Toasty is now more forgiving with FITS and WCS shapes when tiling FITS data
  (#76, @pkgw). In particular, it will behave more correctly when the data and
  WCS shapes disagree, and if the data have interesting structure in the
  non-celestial axes, Toasty will take the first celestial plane it finds rather
  than rejecting the input file.

toasty 0.16.0

toasty 0.16.0 (2022-01-25)

• Add support for some more kinds of longitude arrangements seen in planetary
  maps: "zero left" where the longitude = 0 line is on the left edge of the
  image, rather than in the center, and "zero right" which is comparable except
  that longitude increases to the left, as usually seen in sky maps, rather than
  to the right (#75, @pkgw). These are available in the CLI with the new
  plate-carree-planet-zeroleft and plate-carree-planet-zeroright projection
  types.
• When creating planetary TOAST maps, actually use the planetary TOAST
  coordinate system by default (#75, @pkgw).

toasty 0.15.0

toasty 0.15.0 (2022-01-14)

• Start adding metadata about data min/max values and suggested pixel range cuts
  for tiled FITS data sets, for either TOAST or HiPS-based data processing (#71,
  @imbasimba). This will allow the renderer to provide nice default settings
  when opening up FITS datasets.
• Add support for 32-bit integer FITS (#72, @imbasimba)
• Allow Astropy's WCS code to fix non-standard FITS headers, which increases our
  compatibility with more FITS datasets in the wild (#73, @imbasimba)
• Add the --fits-wcs argument to tile-study, to apply coordinates to an RGB
  image based on the data contained in a separate FITS file (#74, @pkgw). This
  is especially useful if you have an image that Astrometry.Net can solve, since
  that service produces small downloadable FITS files with its solution
  information.
• Reorganize the API docs a bit (#74, @pkgw)

toasty 0.14.0

toasty 0.14.0 (2021-12-13)

• Expand the all-in-one FITS API, toasty.tile_fits, to invoke the
  hipsgen program when given an image that is larger than about 20° on the
  sky (#69, @imbasimba, @pkgw). This is the breakpoint at which WWT's tangential
  projection starts yielding visually poor results.
• Add the toasty view CLI tool the builds on the above, and the new
  scripting support in the resarch app, to act as a command-line FITS viewer
  (#69, @pkgw)! Just run toasty view myfile.fits to view interactively in your
  browser, with sky context and all of the features provided by the research
  app.
• When loading FITS collections, the hdu_index can now be a list of integers,
  instead of just one integer (#69, @imbasimba). This lets you specify different
  image HDUs to use for different input files.
• Various new APIs and internal improvements to enable the above; there's a new
  toasty.fits_tiler module and new interfaces in toasty.collection.
• Add a hack to strongarm AstroPy into being willing to load WCS from improper
  files that include TPV distortions without using the -TPV projection type
  (#69, @pkgw). This allows us to view some of the DASCH FITS files.
