IPs and IP Candidates
For a cataclysmic variable to be confirmed as an Intermediate
Polar, a persistent and stable spin (i.e., non-orbital) periodicity
must be demonstrated. X-ray spin modulation is a great plus, without
which the onus is on the optical observers to demonstrate the stability
of the signal.
