VizieR Online Data Catalog: Planetary nebulae with GALEX, SDSS & PS1 data (Gomez-Munoz+, 2023)

The Hong Kong/AAO/Strasbourg Ha (HASH) database is the most up-to-date catalog of Galactic planetary nebulae (PNs); it includes a compilation of all previous PN catalogs (e.g., Perek & Kohoutek 1967cgpn.book.....P ; Kerber+ 2003, J/A+A/408/1029 ; Parker+ 2006, V/127 ; Stanghellini & Haywood 2010, J/ApJ/714/1096) and is actively ingesting new candidates (or confirmations) of PNs (e.g., Le Du+ 2022, J/A+A/666/A152). We used the coordinates from the HASH database, which gives the positions of 3865 objects with a reported positional accuracy of ~1'. See Section 2.1.

GALEX imaged the sky in the FUV (1344Å-1786Å) and NUV (1771Å-2831Å) simultaneously, with a field of view of 1.2° diameter and a spatial resolution of 4.2" and 5.3", respectively. In this paper, we use data from the GALEX sixth and seventh releases (GR6/GR7; see II/335). See Section 2.2.

SDSS has mapped the sky in five broad bands using a dedicated 2.5m telescope located at the Apache Point Observatory in New Mexico. The telescope used a wide field-of-view camera to acquire the images from 3048Å to 10833Å, in five pass bands: u (3048Å-4028Å), g (3783Å-5549Å), r (5415Å-6989Å), i (6689Å-8389Å), and z (7960Å-10830Å), with a spatial resolution of ~1.4". See Section 2.3.

The PS1 survey used a 1.8m ground-based telescope, located at Haleakala Observatory in Hawaii to image the sky in five broad bands: g_PS1 (3943Å-5593Å), r_PS1 (5386Å-7036Å), i_PS1 (6778Å-8304Å), z_PS1 (8028Å-9346Å), and y_PS1 (9100Å-10838Å), with a field of view of 3°. See Section 2.4.

In the merged match catalog (GUVPNcatxSDSSDR16xPS1MDS) we keep only the "primary" match from each database (GALEX, SDSS, and Pan-STARRS), but we preserve the information on existing additional matches by including ad hoc tags. See Section 2.5.

Of the 3865 PNs in HASH, including confirmed and candidate PNs, 61 are in both GALEX and SDSS, 388 are in GALEX and PS1 Medium Deep Survey (MDS), and a total of 13 PNs were observed by us using the Las Cumbres Observatory Global Telescope (LCOGT) facility (proposal IDs IAC2017AB-004 and IAC2018A-007) in the g' (3968.1Å-5581.5Å), r' (5434.7Å-7085.8Å), and i' (6739.9Å-8350.9Å) bands. See Section 3.3.
