III/5A Faint OB stars between Car and Cen (Lynga 1968) ================================================================================ Catalogue of faint OB stars between Carina and Centaurus Lynga G. =1969ArA.....5..181L =2016yCat.3005....0L ================================================================================ ADC_Keywords: Stars, OB; Stars, faint; Regional catalog Abstract: A survey for faint OB stars between galactic longitudes 290 and 311{deg} has yielded a catalog of 284 objects. Description: The instrument used is the 50/65/175cm Schmidt telescope of the Uppsala Southern Station at Mount Stromlo. The objective prism gives a dispersion of 470Angstrom/mm et H{gamma}. The emulsion has constantly been Kodak IIa-O, the exposure time 20min, and the width of the spectra 0.2mm. A 12 degree zone centered on the galactic equator has been scanned for OB stars. Accurate positions of the stars were added in 2016, using the results from B. Skiff (Lowell Obs.)

Skiff -------------------------------------------------------------------------------- History: * The original catalog was prepared by the author in 1972 (see announcement in 1972BICDS...3....2J) * Standardized documentation in Feb. 2016 at CDS * 15-Mar-2016: the positions of the stars were supplied by B. Skiff [Lowell Obs.]; one star, #138, was recovered from the printed finding chart, at 0.8min in RA from the tabulated position. ================================================================================ (End) Francois Ochsenbein [CDS] 15-Mar-2016
