## Dome CalculationSoon an article by me on the dome azimuth calculations for a side-by-side set-up will be published in the Astronomy Technology Today magazine. The article discusses the maths involved in the proper calculation of the dome slit position for a side-by-side set-up. This page here is to support programmers in testing their implementation of the algorithms. Currently the algorithms are available to a limited group of beta-tester, the calculations below are for REV06 of the manuscript.Conventions: - X-axis: runs north-south, north is positive; - Y-axis: runs east-west, west is positive; - Z-axis: runs vertical, upwards is positive. - Lateral offset: + when OTA is east of centre at park position with the scopes pointing towards Polaris and the counterweight in the direction with an azimuth of 0 degrees. - GEM offset: always positive. All linear measurements can be given in any unit of length as long as the same unit is used for all of them. All linear answers are in the same unit of length as provided. Changing any of below parameters will automatically recalculate the outcome. The pier-side is changed automatically for azimuths between 0° and 180° (pier-side = west) and between 188° and 360° (pier-side = east), but can be changed at will.
