| Moreover, the light reflected by the coelostat is partially polarized, and the amount and character of polarization depends on the incidence angle. |
| It will be laid comfortably flat on the ground, and the rays of light reflected into it by a coelostat. |
| In recent years the Foucault siderostat has been largely supplanted by the heliostat, which is a polar siderostat, and by the coelostat. |
| Back in Ottawa, a specially designed shed with a roll off section housed the coelostat for almost 70 years. |
| This error can be reduced substantially by choosing the coelostat position and time interval. |
| The silvered mirrors of the coelostat were pointed to some of the brighter stars beginning in 1905, and the first large-scale spectra of other stars were obtained. |
