Abstract:
We present final natural-system optical (ugriBV) and near-infrared (YJH)
photometry of 134 supernovae (SNe) with probable white dwarf progenitors
that were observed in 2004-2009 as part of the first stage of the
Carnegie Supernova Project (CSP-I). The sample consists of 123 Type Ia SNe,
5 Type Iax SNe, 2 super-Chandrasekhar SN candidates, 2 Type Ia SNe
interacting with circumstellar matter, and 2 SN 2006bt-like events.
The redshifts of the objects range from z=0.0037 to 0.0835; the median
redshift is 0.0241. For 120 (90%) of these SNe, near-infrared photometry
was obtained. Average optical extinction coefficients and color terms
are derived and demonstrated to be stable during the five CSP-I
observing campaigns. Measurements of the CSP-I near-infrared bandpasses
are also described, and near-infrared color terms are estimated through
synthetic photometry of stellar atmosphere models. Optical and
near-infrared magnitudes of local sequences of tertiary standard stars
for each supernova are given, and a new calibration of Y-band magnitudes
of the Persson et al. (1998AJ....116.2475P 1998AJ....116.2475P) standards in the CSP-I
natural system is presented.
Description:
Between 2004 and 2010, five 9-month CSP-I observing campaigns were
carried out, each running from approximately September through May.
During these campaigns, the vast majority of the optical imaging in
the ugriBV bandpasses was obtained with the SITe3 CCD camera attached
to the LCO Swope 1 m telescope. A limited amount of optical imaging was
also taken with the Tek5 CCD camera on the LCO 2.5 m du Pont telescope.
NIR imaging of the CSP-I SNe during the first observing campaign was
obtained exclusively with the Wide-Field IR Camera (WIRC) on the du Pont
2.5 m telescope (Persson et al. 2002AJ....124..619P 2002AJ....124..619P), and some additional
WIRC observations were carried out during campaigns 2-5. However,
beginning with the second CSP-I campaign, a new imager built especially
for the CSP-I, RetroCam, went into use on the Swope 1 m telescope and
became the workhorse NIR camera for the remaining four campaigns.
