Speckle interferometry of southern double stars. III. Measures from the Cesco observatory, 1994-1996. Horch E.P., Davidson J.W.JR, Van Altena W.F., Girard T.M., Lopez C.E., Franz O.G., Timothy J.G. <Astron. J., 131, 1000-1006 (2006)> =2006AJ....131.1000H
ADC_Keywords: Stars, double and multiple ; Positional data Keywords: astrometry - binaries: visual - techniques: interferometric Abstract: Position angle and separation measures of 482 primarily southern binary stars are presented. These were obtained from speckle observations taken at the Carlos U. Cesco Observatory, El Leoncito, Argentina, using a multianode microchannel array detector during the period 1994 July to 1996 July. Description: A total of eight observing runs were completed with the 0.76m telescope at the Carlos U. Cesco Observatory (jointly operated by Yale Southern Observatory and the Universidad Nacional de San Juan, Argentina). File Summary:

Note (1): Where the RA and Dec (J2000.0) are given in the number with the format HHMM.M±DDMM. Note (2): Flag on FWHM, defined as follows: a = Quadrant ambiguous, but consistent with previous measures in the Fourth Interferometric Catalog (Hartkopf, McAlister, and Mason 2001AJ....122.3480H; see also http://ad.usno.navy.mil/wds/int4/int4.html). b = Quadrant ambiguous, but inconsistent with previous measures in the Fourth Interferometric Catalog. c = Quadrant unambiguous, but inconsistent with previous measures in the Fourth Interferometric Catalog. d = Quadrant unambiguous, but consistency with previous observations is difficult to determine. e = Quadrant ambiguous, but consistency with previous observations is difficult to determine.
