Abstract:
We present the results from CCD photometry in the V, R and
I bands, of the ‘Dipper Asterism’ region of the open cluster Μ67 based
on observations carried out at the prime focus of the 2.3 m Vainu Bappu
Telescope of the Vainu Bappu Observatory, Kavalur. The CCD parameters
like the system gain and the readout noise are measured using several
flatfield frames taken through the standard I filter. The CCD chip is
calibrated using the photometric standards in the field and linear colour
transformation relations are derived. Also a few new VRI photometric
measurements are reported for the members of the cluster.
