## Limited radio pointing determination

Once the optical pointing parameters have been determined and entered in the Antenna-Station file, only one radio pointing on a strong source is needed to get the radio `COV` and the radio `IAZ`. The radio `COH` should be set to its (antenna-only dependent) value.

If the optical `COV` was already well known, you should find the radio `COV = 0`. Radio `IAZ` is determined as follows: measure the azimuth pointing error, divide it by `cos(Elevation)`, and subtract the result from `IAZ` (Oui, soustraire). You should then be ready for a radio observing !
