3D ED tilt series of Pigment Red 5
<p>Electron diffraction tilt series of Pigment Red 5. </p> <p><span>The experimental data were acquired using a 200 kV Glacios transmission electron microscope (Thermo Fisher) operating at liquid nitrogen temperature, employing the EPU-D (Thermo Fisher) module in continuous rotation mode. Electron diffraction patterns were collected in nanodiffraction mode, with an effective beam diameter of 1 µm on the sample. Tilt series were acquired within a goniometer tilt range of -60° to 70°, with a frame interval of 1° and a rotation speed of 0.5 s/1°. A binning factor of 4 was applied to the CETA camera, resulting in an effective pixel size of 0.002 </span><span>Å</span><span>^−1.</span></p>

Multi-regional comparison of scarring and pigmentation patterns in Cuvier's beaked whales
<p>These files represent standardized appearance data from photos of individually-identified, known-sex, adult Cuvier's beaked whales (Ziphius cavirostris) from three distinct study regions. We provide both the original raw datasets and the filtered datasets that were ultimately used in analyses of scarring density and pigmentation patterns to determine the extent to which they are diagnostic of sex in all three regions. The R code used to analyze these files is provided along with detailed descriptions of the data in a README file.</p>
