Abstract | We present new BV photometry for 6564 stars in the field of the globular cluster NGC 6366, using a wide field CCD camera at the prime focus of the Isaac Newton Telescope (INT 2.5m). The mean internal accuracy of the present V magnitudes and (B-V) colours ranges from 0.005mag for the stars at the top of the Red Giant Branch to 0.07mag for the faintest measured Main Sequence stars. From the resultant Colour-Magnitude Diagram (CMD), and considering spectroscopic determinations of [Fe/H] from previous works, we derive ... |
