Surveys Durchmusterungen The Bonner Durchmusterung (BD, Argelander 1859-62, Kuestner 1903, Becker 1951, Schmidt 1968) is a visual survey of stars in the declination zones +89 to -01 degrees. The goal of the survey was to obtain a position and estimated visual magnitude for every star visible with the 78-mm Bonn telescope. Actual magnitude estimates were made and reported to 0.1 mag for all stars down to 9.5 mag, with fainter stars being assigned to 9.5. Positions are given to the nearest 0.1 sec in right ascension and 0.1 arcmin in declination.

The Bonner Durchmusterung (BD, Argelander 1859-62, Kuestner 1903, Becker 1951, Schmidt 1968) is a visual survey of stars in the declination zones +89 to -01 degrees performed by allowing the telescope to drift along the mean declination of each zone and recording the positions and magnitudes of stars crossing the transit line of each field. Actual magnitude estimates were made and reported to 0.1 mag for all stars down to 9.5 mag, with fainter stars being assigned to 9.5. The BD actually contains a rather large number of stars fainter than 10.0 mag. Positions are given to the nearest 0.1 sec in right ascension and 0.1 arcmin in declination. The catalog includes all corrigenda published in the original BD volumes have been incorporated into the machine file, along with changes published by Kuestner and Sticker following the 1903 edition. In addition, stars indicated to be "missing" in published lists and verified by various techniques are flagged so that they can be omitted from computer plotted charts if desired. Stars deleted in the various errata lists have been similarly flagged, while those with revised data are flagged and listed in a separate table. No other corrections or changes have been incorporated into the original data, e.g., from more modern positions and magnitudes or from comparison with other catalogs. The original document (adc.doc) contains substantial additional information.

Roman NSSDC/ADC 1994, modified CDS 20-Sep-1995Nov12This immense project was successfully completed only through the combined efforts of the institutes and individuals listed above and the work of many persons within those institutes. The initial work at the Astronomical Data Center/NSSDC was begun and supervised by Drs. J. M. Mead, T. A. Nagy, and Wayne Warren, Jr. but the punching could never have been begun, nor the project completed without the support of the former NSSDC Director, Dr. James I. Vette. This support continued under Dr. James L. Green, and the Head of NSSDC's Central Data Services Facility, Dr. Joseph H. King. The NSSDC zones (+19 to -01 ) were punched by Beth Alexander, Carol Bergstrom, and Margy Goodwin, while monitoring software for data transfer was written by Frank Barnes and migration to magnetic tape was done by Charleen Perry under the supervision of Ralph Post. ADC software for the formatting of binary data and for the exact reproduction of published pages for proofreading was written by Wayne Warren Jr. but the actual proofing was accomplished by summer students Paula Feldman and Kimberly Kniffen, who also assisted greatly with error checking, recording, and data corrections. Zones +24 and +25 were keyed directly to disk, printed, and proofread by Warren, while B. N. Rappaport arranged for the keypunching of zones +23 to +20 by Syntronix, Incorporated, of Sherman Oaks, California, checked the data with his own computer programs and financed the work himself. The punching of zones +59 to +26 was accomplished at l'Observatoire de Nice by M. Fulconis, under the direction of P. Couteau, and their proofreading was done at the CDS by M. J. Wagner and W. Maslo. Zones +80 to +60 were keyed directly to disk at the CDS by M. J. Wagner, W. Maslo, and R. Bonnet, with preprocessing software written and implemented by F. Ochsenbein. Zones +25 and +24 were also computerized at the CDS and used to check the data prepared at the Astronomical Data Center. Finally, the compilers thank Dr. R. A. Downes of Applied Research Corporation for bringing the "missing" stars to our attention, for supplying a complete list of the stars, and for rechecking certain questionable cases. This document is based on the original ADC document prepared by Wayne Warren Jr. UNKNOWN UNKNOWN The data in the machine-readable Bonner Durchmusterung were keypunched directly from the published catalogs through the collaborative efforts of personnel at l'Observatoire de Nice, the Centre de Donnees Astronomiques de Strasbourg, the National Space Science Data Center at the NASA/Goddard Space Flight Center, and with the help of B. N. Rappaport, then at the NASA Jet Propulsion Laboratory. The following is the distribution of the work: Zones Location +89 to +60 Centre de Donnees Astronomiques de Strasbourg (CDS) +59 to +26 L'Observatoire de Nice +25 to +24 National Space Science Data Center (also CDS) +23 to +20 B. N. Rappaport (+23 also done at CDS) +19 to -01 National Space Science Data Center (+14 also done at Nice) Zones +89 to +60 were also verified at the CDS and zones +59 to +26 were proofread there, while the remaining zones were proofread at the Astronomical Data Center. Redundant zones were compared by computer and appropriate corrections were made. All zones were carefully examined, checked for sequencing and record counts, reformatted, and merged in the correct order at the ADC, where the final catalog was assembled. The supplemental entries were incorporated into the ADC/NSSDC and Rappaport zones from an earlier catalog prepared by Warren and Kress (1980) or used to check existing supplemental entries in the Nice and CDS zones. The published corrigenda lists were cross checked extensively against the reprinted editions of the catalog for preparation of the tables in the appendix of this document. Apparent discrepancies were checked on the BD charts and on the prints of the Vehrenberg Atlas Stellarum. The final catalog was run through a verification program that checked numerical sequencing of the BD numbers, monotonic increase in right ascension, and allowed data ranges. All cases where stars are out of RA order were checked in the original data to verify that their positions are as in the original catalog. The final file is ordered north to south strictly by BD number, i.e., in the zone order +89; +88; ...; -01. Users should note, however, that all stars are not strictly in right ascension order within each zone. This is because individual stars are occasionally out of RA order in the original catalog and because of corrections inserted from the corrigenda. Thus, if the machine catalog is sorted by increasing RA, e.g., for search purposes, some BD numbers will become disordered. *(20-Sep-1995, F. Ochsenbein, at CDS): Three further corrections made on stars: BD+65 820 (was named BD+65 821), BD+65 821 (was named BD+65 821!). BD-00 1000 (a digit was missing in the DEm field) I_122.xml
