-- ABOUT --
Compared with the optical, the exploration of the radio transient sky lags far behind. There is much opportunity for discovery. Hence we have planned a survey of the radio sky with the Jansky VLA, and to use PTF as a resource for a contemporaneous optical survey. We will be observing Stripe 82 with JVLA at four epochs separated by 1 week, 1 month and 1 year. The PTF + JVLA Key Project thus aims at filling the phase space of radio transients with timescales ranging from 1 week to several years.
-- SURVEY SPECIFICS --
The rectangular survey region is bounded by: blc = (329.127,-1.132), trc = (353.158,+1.167)The total area of 50 sq. deg. is split equally among two nights in a given epoch. Each epoch has 14 hours worth of JVLA data and 970 pointings in all. The observations are done between LST 1930h and 0230h. PTF is observing the field at a 1-hour cadence. We are down to a record-breaking duration of about 6 hours for the data reduction and source-cataloging of JVLA data.
