Asteca

Changed

(**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, 183).
- Added an _automatic update checker_ function that notifies the user if an updated version of `ASteCA` is available for download (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).
- Best fit synthetic cluster found is now saved to file (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).
- 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).
- Improved `top_tiers` plotting and saved file (184).

Caveats
- Same as version [0.1.2](https://github.com/asteca/asteca/releases/tag/v0.1.2).

Changed

(**Warning**: this release breaks compatibility with the previous version of the `params_input.dat` file)
- Re-write `lowexp` [error rejection method](https://github.com/asteca/asteca/commit/6b2857aefa2878ee5aba245a7fbf9cc1f423820b), now uses _prediction bands_ instead of _confidence intervals_.
- Force `matplotlib`'s backend to make the code [work in servers](https://github.com/asteca/asteca/commit/197af6439baabd3e9db4039775aba721d84047a2) .
- Fixed `eyefit` method for [error rejection](https://github.com/asteca/asteca/commit/d92be0c8e398739fba562d59ba35b11eeac9a9a0). It changed after fixing #169.
- Added [SDSS CMDs](https://github.com/asteca/asteca/commit/2324a70f402ddbe9fdde203c3745f93b6d6dc545) `g vs (u-g)` & `g vs (g-r)`, at the request of Tjibaria Pijloo (Department of Astrophysics, Radboud University Nijmegen).
- Fixed bug in binarity generation for the CMDs of the form `X vs (X-Y)` (181).
- Smarter selection of stars to be used by the best fit function, improvements in several plots (171, 172).
- Best fit function can now accept a _minimum magnitude_ value instead of just a _minimum probability_ value (115).
- Added a `memb_par` parameter to compare the number of approximate cluster members obtained via the structural analysis and via the decontamination algorithm (162).
- Code is now able to correctly read the names of files with [more than one dot in it's name](https://github.com/asteca/asteca/commit/c0358ed9526b835bfeeddf75804002ad51c69610).
- Fixed bad [alphabetical ordering](https://github.com/asteca/asteca/commit/b6ca2a2df8b7e614dc9beb38e99400e3b69208bf) of input cluster files.
- Better limits for photometric diagram (173).
- Fixed `DeprecationWarning` [issue](https://github.com/asteca/asteca/commit/97d77f1d7f36adf6af6398a2f4a5b944598fda8f).
- Invert x axis when [RA cords are used](https://github.com/asteca/asteca/commit/e99da37a398c446d71c59c43f4547434d0c9f7e7) (improved [here](https://github.com/asteca/asteca/commit/aeb7d7d097eb40289d2bb4c83adf433567bb28d0)).
- Several fixes and improvements made to plotted diagrams ([5c7dc7f](https://github.com/asteca/asteca/commit/5c7dc7f9f348bf2bedb3eb86daf7decbbf83df33); [1642349](https://github.com/asteca/asteca/commit/16423496d22bb843294189fd121a0ed8a0c6e783); [b57028c](https://github.com/asteca/asteca/commit/b57028c93259afbf3cbebc905c482349fcb6ef7a); [240178a](https://github.com/asteca/asteca/commit/240178a3c797910d6a807a41a8dd6c2f94d82cfb); [9ec0ab8](https://github.com/asteca/asteca/commit/9ec0ab8c3d966e0dbe19c6b5cff65e1cb381c939); [fef14c4](https://github.com/asteca/asteca/commit/fef14c476b88bc9f82bcd39e96cee222a0628cdd); [db0df2a](https://github.com/asteca/asteca/commit/db0df2adc8d9821ab5122ba6b6482557627a779e); [575ebe7](https://github.com/asteca/asteca/commit/575ebe7de64c1c4da04eb7c18dfab4b8bd1b2751); #177; 178).

Caveats
- Same as version [0.1.2](https://github.com/asteca/asteca/releases/tag/v0.1.2).

Changed
- Added [_"lazy parallelization"_](https://github.com/asteca/asteca/commit/b536c84c2ad085bbe8ff10a0b6535618ae1ba09a) ability. Now the user can run as many instances of the code as needed simply by creating extra `asteca_xx.py` and `input_xx` folders where `xx` are integers of the form: 01, 02, ..., 99.
- [Reposition](https://github.com/asteca/asteca/commit/e7dec4b75a62ff397ee62cb322345f6b17b74ff6) several text boxes in output images, newer versions of `matplotlib` moved them from the previous position.
- Fix [bad import](https://github.com/asteca/asteca/commit/9bed2166e9cc36faa7077c79c436c50e40801820) of `rpy2` package, positioned incorrectly in two functions.
