n_const.pointing¶
Parse pointing error parameters.
Pointing error is corrected by the following equation:
- class PointingError(**kwargs)[source]¶
Bases:
DataClass
Errors of telescope and its system installation.
Notes
All quantities with [arcsec] are offset or inclination of somewhere in the system. Quantities with [deg] are phases of offsets. Quantities with [dimensionless] are coefficients of polynomial fitting.
