AO-40: updates Keps
Dear All,
All new ranging data continues to be consistent with current estimated keps.
James Miller G3RUH just released some updated data.
Currently things look like this; the fix is based on estimating MA, MM and EC
only, though it is beginning to matter less if WP, RA and IN are allowed to
float:
