Abstract:
The Palomar Transient Factory (PTF) is an optical wide-field
variability survey carried out using a camera with a 7.8deg2 field
of view mounted on the 48 inch Oschin Schmidt telescope at Palomar
Observatory. One of the key goals of this survey is to conduct
high-cadence monitoring of the sky in order to detect optical
transient sources shortly after they occur. Here, we describe the
real-time capabilities of the PTF and our related rapid
multiwavelength follow-up programs, extending from the radio to the
γ-ray bands. We present as a case study observations of the
optical transient PTF10vdl (SN 2010id), revealed to be a very young
core-collapse (Type II-P) supernova having a remarkably low
luminosity. Our results demonstrate that the PTF now provides for
optical transients the real-time discovery and rapid-response
follow-up capabilities previously reserved only for high-energy
transients like gamma-ray bursts.
Description:
PTF10vdl was detected at the 48inch Oschin Schmidt telescope (P48) on
2010 September 15.24 (UT dates are used throughout) and was not
detected in previous images obtained by the survey up to 3.9days
earlier.
After the rapid spectroscopic confirmation of PTF10vdl (Figure 2), we
obtained multiwavelength observations of this object. Swift UV and
X-ray observations were rapidly scheduled, but could not be carried
out until September 18.
Photometric monitoring was carried out using the 1m Wise, 2m LT, P60,
KAIT, and 2m LCOGT Faulkes-North telescopes.

Note (1): All optical ground-based data are calibrated onto the SDSS grid.
Swift data are calibrated following Poole et al. 2008MNRAS.383..627P 2008MNRAS.383..627P.
The P60, LT and Wise gri data calibrate consistently onto the SDSS
grid, while small constant offsets had to be applied to the LCOGT, P48
and KAIT data; values reported here include these offsets.
Note (2): Values of 99.99 indicate that the values in the magnitude column
are upper limits.
