VizieR Online Data Catalog: Circumstellar dust of 104 stars with GPIES (Esposito+, 2020)

We selected our initial list of circumstellar disk targets for the Gemini Planet Imager Exoplanet Survey (GPIES) survey in 2014 February. We observed 104 targets: 96 during the survey, plus an additional 8 that were observed during Gemini Planet Imager (GPI) commissioning.

The GPI is one of the latest generation ground-based adaptive-optics (AO) instruments that are dedicated to the direct detection of extrasolar planetary systems. Located at the Cassegrain focus of the Gemini South telescope (7.8m effective diameter primary).

The GPIES disk survey was conducted using GPI's polarimetric mode. 91 of our observed disk targets were also observed in spec-mode (R~50). 83 of our polarimetric observations are relatively short "snapshots" in order to maximize the number of targets observed. The snapshot data for each target totaled less than 20 minutes of integration time, or about 30 minutes of wall-clock time when considering telescope and instrument overheads. Deep pol-mode observations were identical to snapshots except for longer total integration times, defined as 20 minutes or more. The median integration time was 35.8 minutes across the 36 deep data sets acquired.
