Distributed fiber optics measurements of rock deformation and failure in triaxial tests
<p>We have uploaded two versions of the data. The first version is the raw data from the optical interrogator in the original format. The second version is the processed data. In addition, we have included in each sub-folder a "Readme.txt" file that gives the additional information, requested by the reviewer, on how to process the raw data.</p>

Optical polarimetric observations of black hole binary Cyg X-1 with DIPol-2
<p>The dataset contains raw polarimetric FITS images of black hole X-ray binary <a href="https://en.wikipedia.org/wiki/Cygnus_X-1">Cyg X-1</a> (and surrounding field), obtained with the DIPol-2 optical CCD polarimeter in three (<em>BVR</em>) filters while mounted on the remotely operated Tohoku 60 cm (T60) telescope at the Haleakala Observatory, Hawaii. The data were collected over 5 observing nights during the week 2022 May 15–21 for about 4 hours each night. During each observing night, a set of calibration images were also obtained. These typically include 7 dark and 7 bias images per filter per night. Bias and dark FITS files have `bias` or `dark` labels in their names.</p>
