cds-question@unistra.frpeculiar-variable-starsvisible-astronomymedium-band-photometryDifferential Stroemgren uvby observations from the Four College Automated Photoelectric Telescope (FCAPT) are presented for the mCP stars HD 142070, HR 6967, and HR 8434 and the CP star HR 5341. The latter star is found to be constant. Improved periods were derived for HD 142070, 3.37189d, HR 6967, 3.91227d, and HR 8434, 1.43237d. Further observations of HD 142070 are needed to phase the magnetic data with the photometry, of HR 6967 to settle minor discrepancies between y and scaled Geneva V photometry, and of HR 8434 to resolve small discrepancies between two uvby photometric data sets.2001A&A...368..225Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/368/225CatalogResearchIsServedByTAP 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/111/41 : 56 Tauri, HD 111133, HD 126515 and HD 215441 (North+, 1995)J/A+AS/114/253 : HD 11187, HD 14940, HD 15144, 20 Eri, HR 8933 (Adelman+ 1995)J/PASP/109/9 : HR 1643, Theta Aur, 49 Cam, and HR 3724 (Adelman 1997)J/A+AS/122/249 : HD32633, 25 Sex, HR 7224, and HD 200311 (Adelman, 1997)J/A+A/329/579 : uvby photometry of theta CrB (Fabregat+ 1998)J/A+AS/123/445 : uvby photometry of metallic + Hg-Mn stars (Adelman 1997)J/A+AS/125/65 : HD 37776, HR 2258, HR 6958 & 108 Aqu (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+A/333/952 : BVRI photometry of HR 1105 (Adelman 1997)J/A+AS/134/53 : HD 15980, HR 1094, 33 Gem, and HD 115708 (Adelman 1998)J/A+AS/136/111 : HD 35298, 19 Lyr, HD 192678 and HR 8216 (Adelman+ 1999)J/A+AS/136/379 : 45 Leo, HR 4330, 49 Her and HR 6718 (Adelman+ 1999)J/A+A/357/548 : HD 36668, 36 Lyn, HD 86952 & HR 8861 (Adelman 2000)J/A+AS/146/13 : 20 Eri, HR 1297, 12 CMa & HD 134214 (Adelman 2000)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/A+A/368/225https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/368/225http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/368/225https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/368/225https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/368/225http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/368/225GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/368/225/tableaAverage photometryNameStar namemeta.idcharrecnoRecord number assigned by the VizieR team.
