Limb profiles of the Moon from grazing occultation observations collected at RGO

Soma, Mitsuru; Kato, Yuji

From lunar grazing occultation observations it is shown that the present lunar limb profile data have sometimes large errors, and therefore it is apparent that they need to be modified. For that purpose observations of grazing occultations collected at the Royal Greenwich Observatory until 1980 were analyzed and lunar limb profile data were obtain…

Limb profiles of the Moon obtained from grazing occultation observations.

Soma, M.

Observations of lunar grazing occultations were analyzed using the Hipparcos Catalogue of stars and the JPL planetary and lunar ephemerides DE405, and lunar limb profile data were obtained for future grazing occultation observations. These profile data will be used for the analysis of solar eclipse observations to detect the variation of the solar…

The Tokyo PMC Catalog 90 - 93: catalog of positions of 6649 stars observed in 1990 through 1993 with Tokyo Photoelectric Meridian Circle.

Yoshizawa, Masanori; Suzuki, Shunsaku

The sixth annual catalog of the Toyko PMC is presented for 6649 stars, which were observed at least two times in January 1990 through March 1993. The mean positions of the stars observed in the above period are given in the catalog at the corresponding mean epochs of observations of individual stars. The coordinates of the catalog are based on the…
