摘要: For perfectly aligned heliostats and coelostats tracking at the solar rate half rate, respectively, beam has no translational motion. But, particularly in field eclipses, it is not possible to align with infinite precision. We derive effect of small misalignments on motion beam, give tables allow calculation accuracy which instruments must be mounted adjusted attain a desired over given duration. Further, we show how necessary adjustments improve alignment, measurements error.
