Methods

pixel_to_radec(px, py, attitude, obs_time)	Convert a pixel coordinate to RA/Dec using: - Correct camera geometry - Correct camera -> ECI rotation - Correct TEME -> GCRS conversion
pixel_to_radec_and_vector(px, py, attitude, ...)	Convert a pixel coordinate to RA/Dec and return satellite vector
radec_to_pixel(ra_deg, dec_deg, attitude, ...)	Convert an RA/Dec (ICRS) direction into pixel coordinates (px, py) using the camera's orientation quaternion (w, x, y, z).

pixel_to_radec(px: float, py: float, attitude: CameraAttitude, obs_time: datetime)

Convert a pixel coordinate to RA/Dec using: - Correct camera geometry - Correct camera -> ECI rotation - Correct TEME -> GCRS conversion

pixel_to_radec_and_vector(px: float, py: float, attitude: CameraAttitude, obs_time: datetime, sat_orbit: SatelliteOrbit = None)

Convert a pixel coordinate to RA/Dec and return satellite vector

radec_to_pixel(ra_deg: float, dec_deg: float, attitude: CameraAttitude, obs_time: datetime)

Convert an RA/Dec (ICRS) direction into pixel coordinates (px, py) using the camera’s orientation quaternion (w, x, y, z).

Raises CameraIntrinsicsError if the direction is outside the camera FOV.
