VizieR Online Data Catalog: Swift/UVOT sources in NGC4321 (M100) (Ferreras+, 2012)

We extracted the UV images of NGC 4321 from the archive of the Swift/UVOT mission at HEASARC. The log of the observations can be found in Table 1. In addition to NUV data, we retrieved the optical images from the SDSS/data release 8 (http://skyserver.sdss3.org/dr8) (Aihara et al., 2011ApJS..193...29A). In addition, imaging is available from Spitzer/IRAC and KPNO (Hα). The reduced, calibrated images are taken from the fifth data delivery (2007 April) of the SINGS catalogue (http://sings.stsci.edu) (Kennicutt et al., 2003PASP..115..928K).
