-The interim data product consists of three primary components:
-- Masterfile (`Hyperspectral_data_AAPF_experiment_{Experiment_No}.xlsx`): This file stores the derived phenotypic measurements of the plants and a guide document.
-- HSI Data Processing Quality Control Data (`quality_control`): This directory contains information for quality assessment of the HSI data processing pipeline. It includes summaries of header information for plants, white and dark reference, a detailed record of the processing procedures employed, and animated gif files used to check coregistration quality between visible and near infrared (VNIR) and shortwave infrared (SWIR) data.
