    He used the observatory’s inch Brashear refractor to make micrometric measures of double stars and visual estimates of comparison stars’ magnitudes in variable star fields. As director, he was able to schedule some of his graduate students’ time to the reduction of . Photoplay editions were editions produced to accompany silent films and the early motion pictures of the sound era when movies were known as photoplays. Popular with many book collectors, these books were published mainly in the s and s.

Errata: "Photographic measures of double stars from plates obtained with the 60_cm refractor" [Ann. Bosscha Obs. Lembang, Vol._9, Part_2 ()].

Observation of visual double stars by visual measurement will yield the separation, or angular distance, between the two component stars in the sky and the position howtogetridofbadbreath.club position angle specifies the direction in which the stars are separated and is defined as the bearing from the brighter component to the fainter, where north is 0°.

photographic double star positions, most of which were measured by Hertzsprung, who had retired to Denmark but was eager to continue working. The work was finally completed by Jeffers’ one-time assistant, Stanislaus Vasilevskis, and published two years after Jeffers’ death. Jeffers was married twice, both times to Lick Observatory secretaries.

should, however, be added that photographic measures of double stars and measures with the interferometer have come to the fore as important complements to the ordinary micrometrie measures and promise to be of increasing importance in future work.
