 __Map coordinates:__:: The x (abscissa) and y (ordinate) rectangular coordinates are identified by the **`standard_name`** attribute values **`projection_x_angular_coordinate`** and **`projection_y_angular_coordinate`**, respectively.
 It is assumed that the y-axis is aligned to the Earth's N/S axis, whereas the x-axis aligns with the E/W axis.
 CF specified the standard names **`projection_x_coordinate`** and **`projection_y_coordinate`** for these coordinates prior to version 1.9, but that use is deprecated.
-In the case of this projection, the projection coordinates in this projection are directly related to the scanning angle of the satellite instrument.
+In the case of this projection, the projection coordinates are the scanning angle of the satellite instrument.
 
 __Notes:__:: The geostationary projection assumes a hypothetical view of the Earth from a perspective above the Earth where the azimuth and elevation viewing angles are described using a hypothetical gimbal model.
 This model is independent of the physical scan principles of any observing instrument.
