1.1.0

Added

• Optional argument --lightcurve filename to detrend.py script applying a trend function to a given filename
• Optional argument --sigma sig to detrend.py script which is the standard deviations to filter input data before trend fitting
• Optional argument --lightcurve filename to trim.py script removing the same points for a given filename as for the input file

Changed

• Algorithm to detrend data:
  • Replace Interpolated Univariate Spline with Akima 1DInterpolator which is more flattened between seasons
  • Compute position of nodes using mean values in equal sections instead of usage of KMeans algorithm
• Update varana package to version 1.1.0
• Documentation

Fixed

• Mechanism updating the original data when detrending and trimming is performed on residuals

1.0.0

Added

• Mechanism checking whether a new found frequency can cause that the model does not converge
• Parameters to var.config:
  • LC_NODES_NUMBER
  • FT_STEP
  • FREQ_LINCOMB_MIN_COEFF
  • FREQ_LINCOMB_MAX_COEFF
  • FREQ_LINCOMB_MAX_HARM
• Mechanism to remember the last number of nodes used to detrend the data/residuals
• Dockerfile to run tests locally

Changed

• Algorithm to compute a linear combination of frequencies ❗
• Update varana package to version 1.0.0:
  • Break compatibility with Python 3.5 ❗
  • Migrate to Python >= 3.6
  • Update the algorithm to compute a linear combination of frequencies by freq_comb.py
  • Add max_harm parameter to freq_comb.py and fit.py scripts
  • Remove filterwarnings ignoring the fact that the model can not converge to the data
  • Increase float precision of residuals and after trimming the data from .4f to .7f
  • Refactor code: add type hints, reformat code using Black
  • Change default values in scripts
• Installation script:
  • Root privileges only needed to install the varana package
  • Store a reference to variability-analyser in .bash_profile instead .bashrc
• Documentation

Fixed

• Restart (not overwrite) the residuals file each time when the number of nodes is updated interactively

Removed

• Parameters from var.config:
  • FT_STEP_FACTOR
  • FREQ_LINCOMB_FACTOR
