VizieR Online Data Catalog: Knots in the deep [FeII]+[SiI] image of the SNR Cas A (Koo+, 2018)
Abstract
The narrowband [FeII]+[SiI] filter images and H-band images that we present in this paper were taken with the Wide-Field Camera (WFCAM) on the UKIRT 3.8m telescope in 2013 September. Combining all the images obtained with the two arrays results in an [FeII]+[SiI] image with an effective net exposure time of 10hr and an H image with 0.8hr. This "deep [FeII]+[SiI] image" has a pixel size of 0.2", and its median PSF is 0.7". The 1σ uncertainty in astrometry is 0.104" (or 0.52pix).
