"Selective stimulation of penumbral cones reveals perception in the shadow of retinal blood vessels" – Online Supplemental Material

<em><strong>Selective stimulation of penumbral cones reveals perception in the shadow of retinal blood vessels</strong> </em>(Spitschan, Aguirre &amp; Brainard, 2015) <strong>Online Supplemental Material</strong> Data are provided as CSV (comma separated value) text files with column headers. <strong>RawExperimentalData.csv</strong> – The trial-by-trial data from the main and supplemental rating experiments. Each row corresponds to one trial. <em>Column 1</em> – Experiment (Main or Supplemental)<br><em>Column 2</em> – Observer (DHB, GKA, or MS)<br><em>Column 3</em> – Spectral direction of the modulation<br>L+M – open-field L and M cones<br>L*+M* – penumbral L and M cones<br>L+M+L*+M* – open-field and penumbral L and M cones modulated together<br>S – open-field S cones<br>S* – penumbral S cones<br>S+S* – open-field and penumbral S cones<br>Melanopsin A – Melanopsin A modulation<br>Melanopsin B – Melanopsin B modulation<br>Background – no modulation presented (blank trial)<br><em>Column 4</em> – Temporal frequency (Hz)<br><em>Column 5</em> – Rating (0-3 scale) <strong>Spectra_DHB.csv, Spectra_GKA.csv, Spectra_MS.csv</strong> – Background and modulation spectra used for each of the three observers in the main and supplemental rating experiments. <em>Column 1</em> – Wavelength in nm<br><em>Column 2</em> – Background spectrum (Watts/[m2-sr-wavelength band])<br><em>Columns 3 onward</em> – Positive swing of modulation spectrum for each modulation (Watts/[m2-sr-wavelength band]). Column headers identify modulation using same key as column 3 of the data file described above. <strong>Spectra_Sketch.csv</strong> – Backgound and modulation spectrum viewed by the naive observer who sketched her percepts. <em>Column 1</em> – Wavelength in nm<br><em>Column 2</em> – Background spectrum (Watts/[m2-sr-wavelength band])<br><em>Column 3</em> – Positive swing of modulation spectrum (Watts/[m2-sr-wavelength band])
