VizieR Online Data Catalog: DSSI observations of binaries. VI. Measures in 2014 (Horch+, 2015)

We have started a new program of speckle observations of double stars at Lowell Observatory's Discovery Channel Telescope (DCT), a 4.3-m telescope.

The Differential Speckle Survey Instrument (DSSI) was on the telescope on four occasions during 2014: two nights in March, two in June, eight nights from September 30 to October 7, and four more in November for a total of 16 nights, of which approximately five were used for binary star observations reported here. In Table3, we present our measures of double stars.

There are a number of binaries observed that have orbits of relatively high quality in the Sixth Catalog of Visual Orbits of Binary Stars (Hartkopf et al., 2001AJ....122.3472H) that were not used in the determination of the scale. We may use these to further judge the intrinsic accuracy and precision of the measures in Table3. A listing of these objects is given in Table4, together with the orbit information.

We also estimate the detection limit at 0.2'' in the cases where no companion was found (see Table5).
