v0.1.61

• Forgot to add changes to CHANGELOG.md file. See previous release for changes.

v0.1.6

Changed

• Added "lazy parallelization" 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 several text boxes in output images, newer versions of matplotlib moved them from the previous position.
• Fix bad import of rpy2 package, positioned incorrectly in two functions.
• Fix DeprecationWarning showing when exp_function was used (#169).

Caveats

• Same as version 0.1.2.

v0.1.5

Changed

• Improved radius assignment algorithm (#146). Warning: this breaks compatibility with the previous version of the params_input.dat file.
• Detect cropped cluster region and use correct area when generating field regions (#139, #157).
• Fixed bug that crashed the code when top tiers synthetic clusters with no stars were plotted (#147). Added minimum total mass of 10Mo.
• Fixed bug where KDE p-values for field vs field comparision were artificially increased by comparing a field region with itself (#138).
• Obtain KDE p-value even if one field region is defined (#114).
• Fixed small bug that prevented integrated magnitude curves from being plotted (#145).
• Fixed several smaller bugs and issues (#110, #150, #140, #142, #141, #149, #95, #148, #136, #163, #143).

Caveats

• Same as version 0.1.2.

v0.1.4

Changed

• Improved plotting of crowded fields (#62).
• Function to generate image is now more stable (#112). Re-arranged plots in output image.
• Add Top tiers models output (#130).
• Fixed small bug in KDE p-values function (#134).
• Minor re-arrangement with semi-input data.

Caveats

• Same as version 0.1.2.

v0.1.3

Changed

• Accept arrays of non-equispaced parameter values instead of only equispaced ranges (#121).
• Added support for lognormal Chabrier (2001) IMF.
• More precise encoding/decoding in genetic algorithm.
• Functions separated into sections (#125).
• Input parameters set as global variables (#132).

Caveats

• Same as version 0.1.2.

v0.1.2

Changed

• Likelihood method now supports Dolphin (2002) Poisson likelihood ratio function.
• Closed #120, #101, #129, #124, #102.
• Minor position fix for synthetic cluster text box in output plot.
• Brute force algorithm now returns correct errors.
• Some fixes for when unique values in the input parameter ranges are used [1] [2].
• Replaced deprecated compiler package used to flatten list.

Caveats

• Still not sure why tolstoy likelihood is biased towards high masses 😕

v0.1.1

More stable release.

Changed

• Closed #113, #116.
• Minor change to error function.
• Closed Known issues from previous version.

Caveats

• Same as previous version.

v0.1.0

First semi-stable buggy release

Changed

• Closed #72, #99, #37.
• Changed the way the IMF was sampled, now it should be faster and more precise.
• Some speed improvements (moved things around mainly).
• Binary fraction is now a free parameter.

Known issues

• Serious bug: if the DA is set to run but the Best fit method isn't, the final plot can't be produced since the syn_cl_err function isn't used (fixed in next release).
• Forgotten print prints out mass values every time the E/I operator is applied (fixed in next release).
• If the number of points (n_left) in the radius finding function is smaller than 4, a very small radius is likely
  to be selected. Fixed in next release.

Caveats

• The total initial mass can be set as a free parameter but the likelihood function will select always synthetic clusters of high mass. Thus it is advised to leave this parameter fixed to 1000 solar masses.
• The binary fraction found is not stored in the output data file.
• Some density map plots for mass and binary fraction are missing.

v4.0.0-beta

Changed

• Closed #85, #70, #43, #86.
• Metallicity and age now take steps in the GA.
• Add checker function to make sure certain parameters are set correctly before running.
• Number of points in get_radius increased 20% --> 25% of the RDP (a2e9b8f)

v3.0.0-beta

Changed

• Closed: #89, #77, #80.
• The params_input.dat and semi_input.dat files are now located at the top level next to asteca.py.
• Cluster's photometric files are not longer required to be stored inside a sub-folder to be picked-up by the code.
