The rotation type specifies the meaning of the rotation angle. Only Object and Horizon are typically used for science (or None if your instrument does not have a rotator). ... Mount is typically used for engineering. ... Mount: rotator angle used by the rotator axis controller. ... For an instrument with a rotator: if you specify a rotation type of None and the rotator is moving then it will be halted at approximately its current position; this feature use used to implement a controlled stop. ...

It initiates an optimisation by starting with a grid of theoretical spectra, defined by model or read_grid , a set of starting parameters and an observed spectrum. ... The parameters to be optimised include: T eff , log g , n A , v sin i , v rad being effective temperature, surface gravity, an abundance variable, rotation velocity and radial velocity for one or two stars, and R 2 / R 1 being the relative radius of the second star, if present....

... Teuben, P. J. 2003, in ASP Conf. ... The observed light distribution gives many clues about the different components disk galaxies seem to be made up of (bulge, disk, bars etc.), though it was not until the velocity field of tracer material such as HI in the outer parts of disk galaxies was studied (see Sofue & Rubin, 2001, for an excellent recent review), that an unseen component was postulated to exist. ... Velocity fields are commonly derived from a datacube by fitting gaussians or taking moments...
