data.jl

Functions to import experimental datasets and store them as Jeff.Data objects.

Jeff.read_data — Method

read_data(filename::String; delim=nothing, dq::Float64=0.05, dR::Float64=0.1)

Read experimental data from a file and store in a Jeff.Data object.

Parameters

filename::String : the file path to be read in.
delim::AbstractChar : the delimiting character in the input file. If the file is whitespace delimited, pass nothing. Defaults to nothing.
dq::Float64 : percentage q-vector uncertainty, if not present in file. Defaults to 5..
dR::Float64 : percentage reflected intensity uncertainty, if not present in file. Defaults to 10..

Returns

::Jeff.Data : a data object containing the relevant information.

Jeff.transform — Method

transform(y::Array{Measurements.Measurement}, f)

Perform some transformation on the ordinate axis.

Parameters

y::Array{Measurements.Measurement} : ordinate data (reflected intensity).
f : transformation to perform. Defaults to natural logarithm.

Returns

::Array{Measurements.Measurement} : transformed ordinate.

Jeff.Data — Type

Data(q::Array{Measurements.Measurement}, R::Array{Measurements.Measurement}, resolution::Array{Distributions.UnivariateDistribution}, filepath::String)

The struct for storing experimental datasets.

Parameters

q::Array{Measurement} : the q-vector values, including dq uncertainty.
R::Array{Measurement} : the reflected intensity values, including uncertainty.
resolution::Array{Distributions.UnivariateDistribution} : the resolution function at each q-vector.
filepath::String : the file path for the file.
