 function [dataOUT] = correct_time_baseline(dataIN)
-%CORRECT_TIME_BASELINE Summary of this function goes here
+%CORRECT_TIME_BASELINE UI for basline correction along time axis
-%   Detailed explanation goes here
+%
+%   Usage: [dataOUT] = CORRECT_TIME_BASELINE(dataIN), where dataIN is a
+%   dataset loaded via the LOAD_MATLAB or LOAD_BRUKER function.
+%
+%   The function will show the raw data and offer an input field, where the
+%   number of pretrigger points should be set. By pressing "Apply" the
+%   correction will be executed and the graph changes to the corrected data.
+%   By pressing "Reset" the graph will return to show the original data.
+%   Exit the function by pressing "Done".
