KBSS Data: structure and kinematics of circumgalactic H I

This tarball collects the processed data that are included in Y. Chen et al, 2020, "The Keck Baryonic Structure Survey: Using foreground/background galaxy pairs to trace the structure and kinematics of circumgalactic neutral hydrogen at z~2". Here is how this file is organised. cats - KBSS catalogs as of Jan 2019, organized as FITS tables. This can be slightly different to the most recent KBSS catalog released at ramekin.caltech.edu/KBSS. lya_spec - The stacked spectra near Lya for the KGPS-Full and KGPS- zneb samples.

Wavelengths are included as FITS-WCS in the header. The weight spectra are 1/sigma^2, estimated from bootstrap. These files are used to make Figure 5, and subsequently the 2D optical depth maps. wlya - Lya equivalent width as a function of impact parameter, stored as FITS tables.
