CHARM2: An updated Catalog of High Angular Resolution Measurements We present an update of the Catalog of High Angular ResolutionMeasurements (CHARM, Richichi & Percheron \cite{CHARM}, A&A,386, 492), which includes results available until July 2004. CHARM2 is acompilation of direct measurements by high angular resolution methods,as well as indirect estimates of stellar diameters. Its main goal is toprovide a reference list of sources which can be used for calibrationand verification observations with long-baseline optical and near-IRinterferometers. Single and binary stars are included, as are complexobjects from circumstellar shells to extragalactic sources. The presentupdate provides an increase of almost a factor of two over the previousedition. Additionally, it includes several corrections and improvements,as well as a cross-check with the valuable public release observationsof the ESO Very Large Telescope Interferometer (VLTI). A total of 8231entries for 3238 unique sources are now present in CHARM2. Thisrepresents an increase of a factor of 3.4 and 2.0, respectively, overthe contents of the previous version of CHARM.The catalog is only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/431/773
| Infrared and visual lunar occultations measurements of stellar diameters and new binary stars detections at the Calar Alto 1.5 m telescope We present a program of routine lunar occultations, at optical andnear-IR wavelengths, recently started at the 1.5 m Spanish telescope atthe Calar Alto Observatory. Both a CCD and an infrared array detectorare used. The program is aimed mainly at the detection and investigationof binary systems, although results in other areas of stellar researchare also anticipated. Occultations are reported for a total of 40 stars.Among these, SAO 164567, SAO 78258and AG+24 788 have been discovered to be binaries,with projected separations as small as 0.006 arcsec. Furthermore,binarity is suspected in the case of SAO 78119 andSAO 79251. Additionally, the angular diameter of thelate-type giant 30 Psc and of the infrared starV349 Gem have been accurately measured, the latterfor the first time. We finally evaluate the instrumentation performancein terms of the limiting magnitude and angular resolution, and discussapplications to larger telescopes.Appendix A is only available in electronic form athttp://www.edpsciences.org
