VizieR Online Data Catalog: Ionised gas images of NGC 4569 (Boselli+, 2016)
Abstract
Narrow-band imaging observations were carried out in May 2015 using MegaCam at the CFHT. The galaxy NGC 4569, which has a recessional velocity of -221km/s, was observed in the narrow-band filter MP9603 that was centered on the Hα line (λ= 6590Å; Δλ= 104Å, T=93%).
Long-slit spectroscopy observations were carried out in 2001 with the Calar Alto 3.5m telescope using the Twin spectrograph. Its was observed with the T05 and T06 gratings in the blue (4430Å) and red (6562Å) arm of the spectrograph with a dispersion of 36Å/mm and a spatial sampling of 0.56-arcsec/pixel.
