The ADHOC programme (096.C-0730(A) and 097.C-0749(A), PI G. Beccari) is equivalent to an OmegaCAM mini-survey targeting circumstellar discs in nearby Galactic star-forming regions. The scientific goal of this mini-survey is the study of the star formation history of several star-forming regions using deep, wide field, multi-band observations in the optical filters u, g, r, i and H alpha, with a depth reaching 21 AB magnitudes in r. A total of 8 star-forming regions in the Galaxy were observed.
Data Release 1: Accretion Discs in Halpha with OmegaCam (ADHOC)
Published: 13 Feb 2020
This first data release includes reduced images and single-band sources list for 2 of the 8 in all the available bands. The 2 regions covered by science data products in the current release are gamma Vel (08:09:00 -43:20:00) and Orion A (05:28:00 -07:15:00) for a total of almost 170 square degrees coverage. The products for the additional star-forming regions, including e.g., Lupus, Upper-Sco, Haffner 18, will be made available in future releases.
Data were reduced by CASU and are available via the Science Portal or programmatically. Additional information is provided in the accompanying documentation.
