Abstract:
We present multiband photometry of 60 spectroscopically confirmed
supernovae (SNe): 39 SNe II/IIP, 19 IIn, 1 IIb, and 1 that was
originally classified as a IIn but later as a Ibn. Of these, 46 have
only optical photometry, 6 have only near-infrared (NIR) photometry,
and 8 have both optical and NIR. The median redshift of the sample is
0.016. We also present 195 optical spectra for 48 of the 60 SN. There
are 26 optical and 2 NIR light curves of SNe II/IIP with redshifts
z>0.01, some of which may give rise to useful distances for
cosmological applications. All photometry was obtained between 2000
and 2011 at the Fred Lawrence Whipple Observatory (FLWO), via the 1.2m
and 1.3m PAIRITEL telescopes for the optical and NIR, respectively.
Each SN was observed in a subset of the u'UBVRIr'i'JHKs bands. There
are a total of 2932 optical and 816 NIR light curve points. Optical
spectra were obtained using the FLWO 1.5m Tillinghast telescope with
the FAST spectrograph and the MMT Telescope with the Blue Channel
Spectrograph. Our photometry is in reasonable agreement with select
samples from the literature: two-thirds of our star sequences have
average V offsets within ±0.02mag and roughly three-quarters of our
light curves have average differences within ±0.04mag. The data from
this work and the literature will provide insight into SN II
explosions, help with developing methods for photometric SN
classification, and contribute to their use as cosmological distance
indicators.
Description:
Since all of the optical photometry reported here was produced as part
of the CfA3 and CfA4 processing campaigns, see Hicken+ (2009,
J/ApJ/700/331) and Hicken+ (2012, J/ApJS/200/12) for greater details
on the instruments, observations, photometry pipeline, calibration,
and host-galaxy subtraction used to create the CfA SN II light curves.

Note (1): Number of host-galaxy images subtracted from the same data image.
Nhost=0 means no host-galaxy subtraction was performed and the SN was
sufficiently removed from the host galaxy.
Note (2): The uncertainty is the same as the light curve uncertainty as used
in Hicken+ (2009, J/ApJ/700/331) and is the same as
σ_pipe in Hicken+ (2012A, J/ApJS/200/12).
Note (3): Camera the SN data was acquired with. For CfA4 data, a 1 or 2 is
appended to 'KEP' to indicate if it was taken during period 1 (before
2009 August 15 (MJD=55058) or period 2 (after) and which set of
natural-system bandpasses should be used. The period is of crucial
importance for the color terms used.
