cds-question@unistra.frthe-sunastrometryObservations of the Sun with a modified Danjon astrolabe at 30{deg} and 60{deg} zenith distances have been carried out since 1990 at Santiago, Chile. Here are presented the results in right ascension, parameter Y and apparent semidiameter obtained during the period 1995-1997. These results and those obtained in for mer years are available in electronic form. The differences astrolabe minus ephemeris in {alpha} and semidiameter are briefly discussed.1998A&AS..132..195Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/132/195CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/102/11 : Astrolabe observations of the Sun in 1990-1992 (Noel 1993)J/A+AS/106/327 : Observations of the Sun during 1993 at Santiago (Noel 1994)J/A+AS/106/441 : Second catalogue of Santiago (Noel, 1994)J/A+AS/113/131 : Observations of the Sun during 1994 (Noel, 1995)J/A+A/375/614 : Astrolabe observations of the Sun in 1990-2000 (Noel, 2001)J/A+A/384/650 : CCD solar diameter measurements in 1999-2000 (Penna+, 2002)J/A+AS/135/227 : Solar diameter observations in 1997-1998 (Jilinski+, 1999)J/A+AS/143/265 : Solar diameter observations in 1998-1999 (Puliaev+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/132/195https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/132/195http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/132/195https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/132/195https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/132/195http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/132/195GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/132/195/table2Sun observations at 30{deg} zenith distancerecnoRecord number assigned by the VizieR team.
