  I've been querying the General Catalog of Variable Stars (4th Ed) and
have seen some errors, according with your data. First, there is no entry
for CR Boo; second, V803 Cen is clasified as RCB. CP Eri is UG: (dwarf
nova, right?). Joe Paterson (Columbia University) explained in VSNET that
CR Boo is an AM CVn-type variable, which definition is exactly what for
helium dwarf novae. So, then there are three or four??

  Also, is there any updated edition of GCVS where the new variables and
parameters are introduced? I have downloaded it recently from
cdsweb.u-strasgb.fr. 

  Thanks and good nights... of good observing!
