- Observational: Space density.
- FO Aqr,
IGR J15094-6649, and
as well as other BAT-detected IPs.
- There are 19 CVs that are detected by BAT above a flux threshold of
2.5 x 10-11 and located at Galactic latitude greatre than
5 degrees (|b|>5), and 15 of them are IPs (the other 4 are SS Cyg,
AM Her, BY Cam and V1432 Aql).
Distance estimates for these 15 long-period IPs are evaluated, leading
to an estimate of their space density of
1 (+1, -0.5) x 10-7pc-3. Although these IPs are
at LX ~ 1033 erg/s, there is evidence of a fainter
population (including BAT-detected IPs
YY Dra, and
EX Hya) dominated by short-period
IPs, whose space density may be considerably higher.
