Planetary nebulae (PNe) consist of an ionized envelope surrounding
a hot central star (CSPN) that emits mostly at ultraviolet (UV) wavelengths.
Ultraviolet observations, therefore, provide important information on both the CSPN and the nebula.
We have matched the PNe in The Hong Kong/AAO/Strasbourg
Hα (HASH) catalog with the Galaxy Evolution Explorer
(GALEX) UV sky surveys, the Sloan Digital Sky Survey data
release 16 (SDSS), and the Panoramic Survey Telescope and Rapid
Response System (Pan-STARRS) PS1 second release.
A total of 671 PNe were observed by GALEX with the far-UV
(FUV; 1344-1786Å) and/or the near-UV (NUV; 1771-2831Å)
detector on (GUVPNcat); 83 were observed by SDSS (PNcatxSDSSDR16)
and 1819 by Pan-STARRS (PNcatxPS1MDS). We merged a distilled version of these matched catalogs into
GUVPNcatxSDSSDR16xPS1MDS, which contains a total of 375 PNe with
both UV and optical photometry over a total spectral coverage of ∼1540-9610Å.
We analyzed separately 170 PNe resolved in GALEX images and
determined their UV radius by applying a flux profile analysis.
The CSPN flux could be extracted separately from the PN emission
for 8 and 50 objects with SDSS and Pan-STARRS counterparts respectively.
The multiband photometry was used to distinguish between
compact and extended PNe and CSPNe (binary CSPNe) by
color--color diagram analysis. We found that compact PNe candidates
could be identified by using the
