Fix compatibility issue

This release fixes a compatibility issue with old experiments using scipy.interpolate.interp1d function.

Code optimisations

Thanks to some code optimisation, IceChrono is now ~4 times faster on the AICC2012-VLR experiment.

Fix prior-accu calculation when accu_prior_rep='linear'

• Fix prior-accu calculations when accu_prior_rep='linear'

Fix a crash in the AICC2012-VLR experiment

1.6

Fix the AICC2012-VLR experiment, which was crashing.

A few fixes and improvements

• prior files can now have only two columns
• add option for the representation of accu-prior data points (linear or staircase)
• the sedimentation model only works offline
• more options to the figures
• updates to the documentation

Various improvements

• updates to the documentation
• new option to start from a random initial scenario
• the definition of self.thickness is now optional
• fix for accu and LID prior which extend below the depth grid
• fix calculation of prior near the surface
• fix axis titles
• replace "gas" with "air" everywhere
• fix "couple" with "pair" everywhere
• fix reading of input files with only one line
• fix age axis bounds for ice and air ages

Various improvements

• updates to the documentation
• fixes to make IceChono run on anaconda 2.1.0
• the sigma for the prior can now be defined in the *-prior.txt files, no need to have separate files
• the definition of the correlation matrices for the prior is now optional, we default to the identity matrix
• the figures are now all drawn at the end to reduce memory usage
• various other minor fixes

Correlations included for observations

• we now allow correlation of observations
• switch to AICC2012-VLR exp to save time
• general output.txt file with the run time

First bugs-fixed release in version 1

Bugs fixed:

• removed the dev/ experiment.

A bayesian model to infer a common and optimized chronology for several ice cores

This first release is the basis to infer a common and optimized chronology for several ice cores: it includes the background scenarios and correction functions for accu, LID and thinning, the observations for ice age, gas age, Delta-depth, ice age intervals and gas age intervals and the stratigraphic links in-between the ice cores.
