Abstract:
We present a compilation of UBVRIz light curves of 51 type II
supernovae discovered during the course of four different surveys
during 1986-2003: the Cerro Tololo Supernova Survey, the Calan/Tololo
Supernova Program (C&T), the Supernova Optical and Infrared Survey
(SOIRS), and the Carnegie Type II Supernova Survey (CATS). The
photometry is based on template-subtracted images to eliminate any
potential host galaxy light contamination, and calibrated from
foreground stars. This work presents these photometric data, studies
the color evolution using different bands, and explores the relation
between the magnitude at maximum brightness and the brightness decline
parameter (s) from maximum light through the end of the recombination
phase. This parameter is found to be shallower for redder bands and
appears to have the best correlation in the B band. In addition, it
also correlates with the plateau duration, being shorter (longer) for
larger (smaller) s values.
Description:
This paper presents a sample of multi-band, visual-wavelength light
curves of 51 type II supernovae (SNe II) observed from 1986 to 2003 in
the course of four different surveys: the Cerro Tololo Supernova
Survey, the Calan Tololo Supernova Program (C&T), the Supernova
Optical and Infrared Survey (SOIRS), and the Carnegie Type II
Supernovae Survey (CATS). Near-infrared photometry and optical
spectroscopy of this set of SNe II will be published in two companion
papers.
A list of the SNe II used in this study is presented in Table1.
The first object in our list is SN 1986L and it is the only SN
observed with photoelectric techniques (by M.M.P and S.K., using the
Cerro Tololo Inter-American Observatory (CTIO) 0.9m equipped with a
photometer and B and V filters). The remaining SNe were observed using
a variety of telescopes equipped with CCD detectors and UBV(RI)KCz
filters (see Table5).
The magnitudes for the photometric sequences of the 51 SNe II are
listed in Table4. In every case, these sequences were derived from
observations of Landolt standards (see Appendix D in Hamuy et al.
2001ApJ...558..615H 2001ApJ...558..615H for the definition of the z band and Stritzinger
et al. 2002AJ....124.2100S 2002AJ....124.2100S for the description of the z-band
standards). Table5 lists the resulting UBVRIz magnitudes for the 51
SNe.

--------------------------------------------------------------------------------
Note (1):
We compute differential photometry of the SN with respect to a local
sequence of stars calibrated relative to standard star observations
obtained over multiple photometric nights. For this, we measured
instrumental magnitudes of the SN and the local sequence stars via PSF
fitting when the SN was faint, or simple aperture photometry when the
object was bright. The transformation of the instrumental magnitudes to the
standard UBV(RI)KCz system assumes a linear term in magnitude, a color
term, and a photometric zeropoint:
X=x+CTX+ZPX (Eq. (1) in the paper), where
* X represents the standard system magnitude;
* x is the instrumental magnitude;
* the color term CTX is an average measured over many photometric nights
for each telescope/CCD/filter combination;
* the zeropoint ZPX is a fitting parameter determined from all the local
standards.
In every case, the sequences were derived from observations of Landolt
standards (see Appendix D in Hamuy et al. 2001ApJ...558..615H 2001ApJ...558..615H for the
definition of the z band and Stritzinger et al. 2002AJ....124.2100S 2002AJ....124.2100S for the
description of the z-band standards).
