VizieR Online Data Catalog: Transit time of K2-146b and K2-146c with K2 and HPF (Lam+, 2020)

The K2 photometric observations were obtained between 2015 April 27 and 2018 July 2, spanning a baseline of almost 1200 days. The K2 target pixel data were downloaded from the Mikulski Archive for Space Telescope (MAST).

We obtained spectra with the Habitable-zone Planet Finder (HPF) between 2019 February 22 and 2019 May 9. HPF is a high-resolution (R=55000) precision-fiber-fed, near-infrared (NIR) spectrograph recently installed on the Hobby-Eberly Telescope, covering the information-rich z, Y, and J bands (810-1280 nm).

The methods used to extract the transit times is describe in section 4 of the article.
