Abstract:
We present broad-band UBV(RI)c CCD imagery of 334 stars in the
direction of the Galactic cluster Haffner 19. The sample is complete
to mλ=19 (λ = U, B, V, R, I). We reliably establish the
cluster membership for 102 stars based upon their locations in the
(V, B-V), (V, V-I), (I, R-I), (U-B, B-V), and (V-R, V-I) diagrams,
thus increasing three-fold the number of known cluster members. With
the Q-method we determine the MK spectral types of the 33 brightest
stars, confirming that 29 belong to the cluster's young population
(15 B0-B1 and 14 B2- B9 main sequence stars). Complementary uvbyβ
photoelectric photometry of 6 bright stars independently confirms the
distance and reddening to the cluster.
Description:
Observations were made on 1996 December 6 at the 1.5m "Harold L.
Johnson" telescope of Sierra San Pedro MArtir National Astromonical
Observatory.
Coordinates, which are not in the original paper, have been added
by B. Skiff (Lowell Observatory) for about 270 of the 331 stars.
Remarks resulting from this work are added in the 'Rem2' column.
