An extensive search for rapid optical variability in ultracool dwarfs
(Oxford University Press, 2013)
In this paper, a summary of optical time-series photometry of 125 ultracool dwarfs is given.
The observing strategy was to monitor each object continuously for 2–3 h in order to ascertain
whether itwas rapidly variable. ...
Linking multi-epoch CCD photometry of partially overlapping fields
(Oxford University Press, 2013)
A common problem in CCD photometry is to combine measurements obtained at different
epochs. This is especially challenging if the fields only overlap partially, and are sparse, so
that not all calibrating stars are ...
