- •
The spectra of all investigated systems are as expected for their respective class.
- •
The orbital ephemeris of LS IV lsi1" class="mathmlsrc">−08° 3 have been improved.
- •
Doppler mapping of LS IV lsi1" class="mathmlsrc">−08° 3 reveal distinct emission sites (outer accretion disk and illuminated secondary star).
- •
Tentative orbital periods of 0.21462 days and 0.229 days are derived for HQ Mon and ST Cha, respectively.
- •
Light curves of all systems are discussed.
