Notes. Decline rates were obtained by fitting a first degree polynomial to all epochs post peak for a given filter. Peak magnitude for all bands except for the I band are given as ranges, where the upper limits have been extrapolated from the decline rate fit at the JD of I-band maximum, since they lack data at peak. We consider the fit values to be upper limits since a concave-down light curve would have a dimmer peak than this fit indicates. The lower limits are simply the magnitude of first detection immediately after peak. The peak magnitude values have not been extinction corrected.
