G. private communications (1999-2006) * this list only! -------------------------------------------------------------------------------------------------------------------------------------- * General notes about discovery precedence: Not all clusters listed here are original Alessi's discoveries or aren't officialy known under Alessi name. Some of them are independent discoveries or re-discoveries, e.g. Alessi 7 = BH 164 and Alessi 79 = NGC 5045. Alessi 25, 39, 41 and 47 were first published by Kharchenko et al under ASCC designation, without Alessi aliases. They were reported by Alessi only to the DSH site. The remaining clusters ( Al or Al-Te ) that have ASCC designations were also first published by Kharchenko et al., but they provided an additional table showing the respective Alessi and Al-Te names for them. This clusters were reported by Alessi only to the online DAML catalog and DSH site (and for Al 34 in a poster in a SAB symposium). Alessi 1 was first discovered by Glenn LeDrew, but it is officially known under Alessi designation because the paper 2003A&A...410..565A were published before LeDrew's paper, which is still unpublished. At that time, Alessi wasn't aware of LeDrew's discoveries. Several observers ( Laurent Ferrero, Jaakko Saloranta, Philipp Teutsch ) also noticed this cluster, but they did not publish their results. There are another Alessi objects that were also discovered by LeDrew, but Glenn reported his discoveries only to the book 'Star Clusters'. Some Alessi-Teutsch were originally discovered by Philipp Teutsch, but since Alessi first noticed their possible cluster status, Philipp kindly suggested him to name them 'Alessi-Teutsch' (e.g. A-T 09). Some of them are idependent discoveries made by both astronomers and they aggreed in naming them 'Alessi-Teutsch' (e.g. A-T 05). * General notes about fundamental parameters: For all clusters that have ASCC or COCD designations (except Al 10), the adopted coordinates, diameters and fundamental parameters comes from Kharchenko et al. -------------------------------------------------------------------------------------------------------------------------------------- TODO: complete & revise it Comments: 1 besides Alessi and LeDrew, several other observers noticed this object: Teutsch, Ferrero, Saloranta 6 close pair with BH 164 (center to center sep: 51') 10 COCD core & corona diameters are clearly underestimated.

(after the acronym) adds uncertainty to the classification. e.g. 'OC?' = 'Possible open cluster' / signals uncertaing between two classifications. e.g. 'OCR/MUL' could be read as 'Likely open cluster remnant (that contains a multiple) or only a multiple star system suporimposed on a rich field' -------------------------------------------------------------------------------------------------------------------------------------- Discovery methods (TODO): URA Uranometria2000 charts DSS Digital Sky Survey Images (DSS-I, DSS-II) PSS POSS I-Prints 2MA 2MASS-Survey Images KER Kernel cluster-detection program HYP HyperSky (planetarium software) plotting GSC catalog SKV SkyView (planetarium software) plotting TYCHO-2 and HIPPARCOS catalogs Vnn Visual discovery with telescope of diam = 'nn' (inches) --------------------------------------------------------------------------------------------------------------------------------------
