ZTFJ175505.10+132519.6 = ZTF18abdjpbo (polar): Porb
From ZTF data. Porb = 0.0571071(1) d.
Three humps per period (1.0 mag, rather complex).
Probably eclipsing (more than 1.0 mag).
ZTFJ060914.52+400601.5 = ZTF18abuxzdj (polar): Porb
From ZTF data. Porb = 0.0927243(2) d.
Three humps per period (rather complex). Full amplitude
1.2 mag.
ZTF18abbxmwt (likely polar): Porb
From ZTF data. Porb not very clear, but Porb=0.0875885(1)
looks likely (with variable orbital profile?).
1.0-mag large orbital variation with two humps.
