Up: Measurements of double stars 1998.13
The observing program comprises the following double stars:
- long period binaries with non-definitive orbital elements, but considerable
annual motion,
- wide pairs, which have not been measured for many years
- close pairs not observed by Hipparcos.
In the lists one will find many pairs with first class orbits as well as pairs
having been measured by Hipparcos or recently by Speckle. It was, however, the
author's intention to get as many calibration measurements as possible during
the first two years of micrometer measurements with the Cassegrain.
