Asteca

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

(**Warning**: this release breaks compatibility with the previous
version of the ``params_input.dat`` & ``semi_input.dat`` files)

- Models (ie: isochrone + extinction +distance modulus + mass
distribution + binarity) are now evaluated *each time the GA selects
them as a solution*, thus a new mass distribution is generated
(`186 <https://github.com/asteca/asteca/issues/186>`__). This has a
performance cost, but provides higher accuracy in the best model
assignment process since a single model can now be evaluated with a
slightly different mass distribution several times (only with GA,
*Brute Force* method will only process a model once).
- Added an *exit switch* to the decontamination algorithm. It will stop
iterations if the MPs converged to 0.1% tolerance values for all the
stars in the cluster region (compared to the previous iteration).
This speeds up the function considerably
(`185 <https://github.com/asteca/asteca/issues/185>`__).
- The upper mass value in the IMF can now be `modified via the input
parameters
file <https://github.com/asteca/asteca/commit/4b1a897d69cf85b1c0263d738cf2132d9924eb9c>`__.
- Code can now read ``params_input_XX.dat`` files when `using lazy
parallelization <https://github.com/asteca/asteca/commit/f2508355d8136c2d5a6216093e6f9eda02bd99c1>`__.
- Number of field regions `can now be set
individually <https://github.com/asteca/ASteCA/commit/dc4c9223b0ec0a02904e30025eec50dfdc13637d>`__
via the ``semi_input.dat`` file.
- `Added ‘bb’ binning
method <https://github.com/asteca/ASteCA/commit/d35c5611708d249e730bef77b0ee14226cce14de>`__
based on `Bonnato & Bica
(2007) <http://adsabs.harvard.edu/abs/2007MNRAS.377.1301B>`__. Sets
bin widths of 0.25 and 0.5 for colors and magnitudes respectively.
- Fixed bug in ``manual`` mode when `displaying
errors <https://github.com/asteca/asteca/commit/2e4b1d8f8a084e78bc56d52df494a796a6909de6>`__.
- Fixed bug when narrow frames were plotted
(`168 <https://github.com/asteca/asteca/issues/168>`__).
- Moved text box outside of synthetic cluster’s plot to improve its
visibility (`205 <https://github.com/asteca/asteca/issues/205>`__).
- Closed `13 <https://github.com/asteca/asteca/issues/13>`__. Saha’s W
likelihood needs the number of model points to be fixed, which
prevents it from being used when the mass varies. There’s nothing to
be gained by adding this function.
- Caveat dragged from version

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

(**Warning**: this release breaks compatibility with the previous
version of the ``params_input.dat`` file)

- Added ``local`` and ``mp_05`` methods to the selection of which stars
to use in the best fit cluster parameter assignation process
(`180 <https://github.com/asteca/asteca/issues/180>`__,
`183 <https://github.com/asteca/asteca/issues/183>`__).
- Added an *automatic update checker* function that notifies the user
if an updated version of ``ASteCA`` is available for download
(`179 <https://github.com/asteca/asteca/issues/179>`__).
- Added grid lines over the photometric diagrams of the observed and
synthetic cluster, showing the binning made by the method selected in
each case (`131 <https://github.com/asteca/asteca/issues/131>`__).
- Best fit synthetic cluster found is now saved to file
(`154 <https://github.com/asteca/asteca/issues/154>`__).
- Correctly obtain approximate number of members (``n_memb``) and
contamination index (``CI``) when the cluster radius extends beyond
the RDP, thus making the field star density value (``field_dens``)
unreliable (`111 <https://github.com/asteca/asteca/issues/111>`__).
- Added ``f10`` flag to alert when the ``memb_par`` value is greater
than +-0.33, which means that there are twice as many estimated true
members in either method
(`175 <https://github.com/asteca/asteca/issues/175>`__).
- Improved ``top_tiers`` plotting and saved file
(`184 <https://github.com/asteca/asteca/issues/184>`__).

of input cluster files.

- Fixed ``DeprecationWarning``
