For GRB 130215A/SN 2013ez, we also present optical spectroscopy at t-t0=16.1d, which covers rest-frame 3000-6250{AA}. Based on FeII (5169) and SiII (6355), our spectrum indicates an unusually low expansion velocity of 4000-6350km/s, the lowest ever measured for a GRB-SN. Additionally, we determined the brightness and shape of each accompanying SN relative to a template supernova (SN 1998bw), which were used to estimate the amount of nickel produced via nucleosynthesis during each explosion. We find that our derived nickel masses are typical of other GRB-SNe, and greater than those of SNe Ibc that are not associated with GRBs. For GRB 130831A/SN 2013fu, we used our well-sampled R-band light curve (LC) to estimate the amount of ejecta mass and the kinetic energy of the SN, finding that these too are similar to other GRB-SNe. For GRB 130215A, we took advantage of contemporaneous optical/NIR observations to construct an optical/NIR bolometric LC of the afterglow. We fit the bolometric LC with the millisecond magnetar model of Zhang & Meszaros (2001ApJ...552L..35Z), which considers dipole radiation as a source of energy injection to the forward shock powering the optical/NIR afterglow. Using this model we derive an initial spin period of P=1ms and a magnetic field of B=1.1x10^15^G, which are commensurate with those found for proposed magnetar central engines of other long-duration GRBs. Description: The data in file 'table3.dat' are the apparent magnitudes of the afterglow+supernova+host (combined), which are not corrected for foreground or rest-frame extinction. Note that the ROTSE magnitudes are unfiltered calibrated to sdss_r_.
