Keck Planet Finder: design updates

The Keck Planet Finder (KPF) is a fiber-fed, high-resolution, high-stability spectrometer in development at the UC Berkeley Space Sciences Laboratory for the W.M. Keck Observatory. KPF is designed to characterize exoplanets via Doppler spectroscopy with a goal of a single measurement precision of 0.3 m s-1 or better, however its resolution and stability will enable a wide variety of astrophysical pursuits. Here we provide post-preliminary design review design updates for several subsystems, including: the main spectrometer, the fabrication of the Zerodur optical bench; the data reduction pipeline; fiber agitator; fiber cable design; fiber scrambler; VPH testing results and the exposure meter

Mouse Action Recognition System (MARS) trained models, version 1.8

This dataset contains trained neural network models for mouse detection and pose estimation, and trained classifiers for mouse behavior annotation. These model files accompany the MARS end-user software posted at https://github.com/neuroethology/MARS, for MARS version 1.8. To use these trained models, download the models.zip file and unzip into MARS/mars_v1_8/models. See https://github.com/neuroethology/MARS for documentation on using these models from within MARS. We also include two short sample videos of interacting mice (in sample_videos.zip) that can be used to test your MARS installation.Related Publication: The Mouse Action Recognition System (MARS): a software pipeline for automated analysis of social behaviors in mice Segalin, Cristina Caltech Williams, Jalani Caltech Karigo, Tomomi Caltech Hui, May Caltech Zelikowsky, Moriel Caltech Sun, Jennifer J.
