title: MetTLM 20NRM01 TU/e Dataset: Dependence of Temporal Frequency and Chromaticity on the Visibility of the Phantom Array Effect

description: The dataset has the following format: 20 (Participants) by 18 (= 3 Chromaticities × 6 Temporal Frequencies)

Chromaticities:              Red (R); Green (G); Warm White (W)

Temporal Frequencies: F1 = 80 Hz; F2 = 300 Hz; F3 = 600 Hz; F4 = 900 Hz; F5 = 1200 Hz; F6 = 1800 Hz.

Due to the fractional factorial 3 (colour) × 6 (temporal frequency) mixed design, there are some empty cells. The details are described in Table 2 of the publication.

The values in the table represent the visibility thresholds in Modulation Depth (MD). For example, the values of 0.05, 0.1, and 1 means a MD of 5%, 10% and 100% respectively.
description: This MATLAB code can be used to generate Figure 4 (together with the options of 1) printing out the coefficients and goodness-of-fit of the 3rd-order polynomial fits; 2) visualizing the peak sensitivities and peak frequencies according to the 3rd-order polynomial fits) in the publication:

description: This study was part of the HTI (Human-Technology Interaction) Research Project and was partially supported by the Human-Technology Interaction (HTI) group at Eindhoven University of Technology (TU/e). 

In addition, the study was executed within the MetTLM-project (i.e,   Metrology for Temporal Light Modulation; 20NRM01) and received funding from the EMPIR (European Metrology Programme for Innovation and Research) programme co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation programme.
