HR 1643 (P=2.73475d) shows large phase variability in all four magnitudes. Theta Aur (P=3.6188d) exhibits large amplitude variations with two components contributing to the minima. For 49 Cam (P=4.28679d), we probably are observing both polar regions and much of the surface. The values for HR 3724 (P=33.984d) confirm Wolff's result that the main variability is in v.1997PASP..109....9Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/109/9CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/1 : 63 And, HD 192913, HR 8240 & 108 Aqr (Adelman+ 1994)J/A+AS/106/333 : Alpha And, HD 184905, HR 8216 & HR 8434 (Adelman+ 1994)J/A+AS/114/253 : HD 11187, HD 14940, HD 15144, 20 Eri, HR 8933 (Adelman+ 1995)J/A+AS/122/249 : HD 32633, 25 Sex, HR 7224 & HD 200311 (Adelman, 1997)J/A+AS/125/65 : HD 37776, HR 2258, HR 6958 & 108 Aqr (Adelman, 1997)J/A+AS/125/497 : Theta Vir and 109 Vir uvby photometry (Adelman 1997)J/A+AS/128/245 : AR Aur, 3 Hya, 49 Cnc & BX Boo (Adelman 1997)J/A+AS/133/197 : 33 Tau, HD 50169 and HR 7786 (Adelman+ 1998)J/A+AS/134/53 : HD 15980, HR 1094, 33 Gem and HD 115708 (Adelman 1999)J/A+AS/136/111 : HD 35298, 19 Lyr, HD 192678 and HR 8216 (Adelman 1999)J/A+AS/146/13 : 20 Eri, HR 1297, 12 CMa, and HD 134214 (Adelman, 2000)J/A+A/368/225 : HR 5341, HD 142070, HR 6967 & HR 8434 (Adelman, 2001)J/A+A/390/1023 : HR 194, HD 32966, HD 171782, and HR 7911 (Adelman+, 2002)J/A+A/401/357 : 60 Tau, HR 1528, HR 8216, HR 8770 (Adelman+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/109/9https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/109/9http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/109/9https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/109/9https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/109/9http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/109/9GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/PASP/109/9/table2uvby Photometry for HR 1643v(ch-c)check-comparison (ch-c) v magnitudemagphot.mag;arith.difffloaty(v-c)variable-comparison (v-c) y magnitudemagphot.mag;arith.difffloaty(ch-c)check-comparison (ch-c) y magnitudemagphot.mag;arith.difffloatb(ch-c)check-comparison (ch-c) b magnitudemagphot.mag;arith.difffloatv(v-c)variable-comparison (v-c) v magnitudemagphot.mag;arith.difffloatrecnoRecord number assigned by the VizieR team.
