'Monitor' NGC 2547/WFI Data Release: Version 1.0
Monitor NGC 2547 data release: Version 1.0
As part of the Monitor project
(Aigrain et al. 2007, MNRAS, 375, 29), a time-domain survey of NGC
2547 was carried out in I-band using the ESO Wide Field Imager mounted
on the 2.2m telescope at La Silla, Chile. The survey covers two
fields, or ~0.6 sq. deg, observed as adjacent WFI pointings, with a
small overlap (~10%). The majority of the survey consists of the
I-band time-domain component, observed with a cadence of ~7 minutes.
Exposures in V and R bands were also obtained during photometric
conditions and good seeing, to produce colour-magnitude diagrams.
All of the data fall under the large programme 175.C-0685, which also
includes a similar survey in Blanco-1 (incomplete), and was intended
to include a further survey in NGC 2516, which has since been dropped.
The first publication using these data is Irwin et al. 2007, MNRAS,
submitted (title "Rotation of low-mass stars in the open
cluster NGC 2547"), which contains a membership and rotation
analysis, in addition to a description of the reductions.
