For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...

. Text is deleted by combining the delete commands x and d with the type of text object to be deleted. Numbers can also used with both the x and d commands to delete multiple instances of a text object. For example: 5dw . This deletes the current word and the following four words. Deleting characters . Deleting words and lines . Deleting sentences and paragraphs . Undeleting text .

... The first column shows the kinematical diagrams, where is the angle between the line of sight on the object and the vector of rotation about Z -axis, and V S is objects line-of-sight velocity relative to an observer at rest at the position of the Sun. The straight lines are regression fits, whose slopes yield the subsystem’s rotation rate. The second column shows the relations between metallicity and distance from the Galactic plane. ... privious figure | next figure . ...
