VizieR Online Data Catalog: Gemini-LIGHTS protoplanetary disks (Rich+, 2022)

We present the Gemini-LIGHTS survey, which observed 44 bright Herbig Ae/Be stars and T Tauri stars with the GPI instrument at Gemini South. We constructed our sample based on their near- and mid-infrared colors selecting a number of transitional, pre-transitional, and full disks in order to create an unbiased sample. Importantly, we did not select against unequal mass binaries with moderate separations. Observations of these 44 targets were taken in J and H bands utilizing high-contrast polarized imagery. Our selection criteria facilitate an unbiased approach to studying bright Herbig Ae/Be and T Tauri stars that does not favor famous targets with large disks (>100au).

We define a standard FITS file for high-contrast polarization data. This is motivated by large numbers of observations of protoplanetary disks from multiple telescopes (e.g., GPI, SPHERE/IRDIS, Subaru/HiCIAO, Subaru/CHARIS). A standard FITS file will allow for better comparison of protoplanetary disk polarization imagery between different studies and instruments. This FITS standard was created in collaboration with Christian Ginski.

The data are held in a three-dimensional cube of 5*x*y, where x and y are the pixel dimensions of the image, and 5 are the different image types. The five different image types are I, Q_phi, U_phi, Q, U, and :LP_I where I is the intensity image without stellar light subtracted, Q_phi, U_phi, Q, and U as defined above in Section 3, and LP_I, which is the linear polarized intensity or (Q²+U²)^1/2..
