VizieR Online Data Catalog: Hα imaging survey of the 40% ALFALFA HI LSBGs (Lei+, 2019)
Abstract
Based on the selection of 1129 low surface brightness galaxies (LSBGs) from the α.40-SDSS DR7 of Du2015 (Du+ 2015AJ....149..199D), 468 Hα images of LSBGs are presented here. Lei+ 2018ApJS..235...18L already presented the first results for 111 LSBGs in the fall sky region.
All the Hα and R images are observed using BAO Faint Object Spectrograph and Camera instrument (BFOSC) attached to the 2.16m telescope at the Xinglong Observatory of the National Astronomical Observatories, Chinese Academy of Sciences (NAOC). There are 11 Hα filters whose central wavelengths range from 6533 to 7052Å with a FWHM of ~55Å and the Hα image observation is from 2013 to 2017. (2 data files).- Publication:
