Raw data files for "Estimating the effect of cooling rate on the acquisition of magnetic remanence"

# Desciption of the data.

The following data set is a collection of TRM acquisition curves in different cooling and field regimes for a selection of grain sizes and elongations. The data is arranged in a direcotory structure in the following way, once the 'sd_cooling_data.zip' file has been unpacked

sd_cooling_data/
|
+-- pc
    |
    +-- nm
        |
        +-- uT

                +-- 6.00es

                    +-- model.csv

The model.csv file is a comma delimited file consisting of four columns:
    column 1 - the time in seconds as the grain population cools,
    column 2 - the temperature in degrees centigrade,
    column 3 - the 'cooled magnetization' of the population i.e. each grain experiences each temperature step for a finite amount of time,
    column 4 - the 'equilibrium magnetization' of the population i.e. each grain experiences each temperature step for an infinite amount of time.

# Reproducing the data.

Each model takes a JSON file as input to control its behaviour. Running the model is described on the 'sd-cooling' repository home page
