VizieR Online Data Catalog: Type Ia supernova 2011de UVOT photometry (Brown, 2014)

SN 2011de was observed with the Swift spacecraft beginning 2011 May 28.2. Photometry was obtained in six UV and optical bands (see Roming et al. 2005SSRv..120...95R and Poole et al. 2008MNRAS.383..627P for filter details). Swift UVOT data were analyzed using the reduction method of the Swift Optical/Ultraviolet Supernova Archive (Brown et al. 2014, Ap&SS, 354, 89). This includes subtraction of the underlying galaxy flux and uses the revised UV zeropoints and time-dependent sensitivity from Breeveld et al. (2011AIPC.1358..373B). For simplicity we will focus on three filters with which to study colors and absolute magnitudes. We use uvm2 for the mid-UV, u for the near-UV (or NUV), and the v band for the optical. This is similar to Brown et al. (2014ApJ...787...29B) with u being substituted for uvw1 because the long optical tails of the uvw1 filter complicate the comparison of objects with different spectral shapes.
