A multi-resolution, multi-epoch low radio frequency survey of the Kepler
  K2 mission Campaign 1 field
  We present the first dedicated radio continuum survey of a Kepler K2 mission
field, Field 1 covering the North Galactic Cap. The survey is wide field,
contemporaneous, multi-epoch, and multi-resolution in nature and was conducted
at low radio frequencies between 140 and 200 MHz. The multi-epoch and ultra
wide field (but relatively low resolution) part of the survey was provided by
15 nights of observation with the Murchison Widefield Array (MWA) over a period
of approximately a month, contemporaneous with K2 observations of the field.
The multi-resolution aspect of the survey was provided by the low resolution
(4') MWA imaging, complemented by non-contemporaneous but much higher
resolution (20") observations using the Giant Metrewave Radio Telescope (GMRT).
The survey is therefore sensitive to the details of radio structures across a
wide range of angular scales. Consistent with other recent low radio frequency
surveys, no significant radio transients or variables were detected in the
survey. The resulting source catalogs consist of 1,085 and 1,468 detections in
the two MWA observation bands (centered at 154 and 185 MHz, respectively) and
7,445 detections in the GMRT observation band (centered at 148 MHz), over 314
square degrees. The survey is presented as a significant resource for
multi-wavelength investigations of the more than 21,000 target objects in the
K2 field. We briefly examine our survey data against K2 target lists for dwarf
star types (stellar types M and L) that have been known to produce radio
flares.
