6029A VI/29A Finding list for multiplet tables of NSRDS-NBS 3 C J Adelman S J Adelman D Fischel W H Warren Jr. Astron. Astrophys. Suppl. Ser. 60 339 1985 1985A&AS...60..339A Atomic physics Multiplet Spectroscopy The primary references for stellar line identifications in the optical and ultraviolet spectral regions have been "A Multiplet Table of Astrophysical Interest" (RMT, Moore 1945) and "An Ultraviolet Multiplet Table" (UMT, Moore 1950, 1952, 1962). Dr. Charlotte Moore Sitterly has, over the last two decades, undertaken a revision of certain multiplet tables based on data derived from analyses of optical spectra. The present finding list has been prepared from the data published in the first ten sections of these revised tables: -------------------------------------------------- Section Year Elements -------------------------------------------------- 1 1965 Si II, Si III, Si IV 2 1967 Si I 3 1970 C I, C II, C III, C IV, C V, C VI 4 1970 N IV, N V, N VI, N VII 5 1975 N I, N II, N III 6 1972 H I, D I, T I 7 1976 O I 8 1979 O VI, O VII, O VIII 9 1980 O V 10 1983 O IV -------------------------------------------------- An earlier finding list containing Sections 1-7 only was published by Adelman, Adelman and Fischel (1977) (Catalogue VI/11). We have revised the format and added information to the earlier list, and have appended Sections 8-10 to produce the present version. We intend to incorporate future sections to produce new comprehensive lists as the sections are published and can be computerized. This document describes the machine version of the finding list as it is currently being distributed from the Astronomical Data Center. It is intended to enable users to read and process the data without problems and guesswork, and to interpret the various codes used in the list without recourse to the original publications. However, for additional details concerning the multiplet tables and analyses of the optical spectra, the source publications and their associated references should be consulted.

El Element (D=Deuterium, T=Tritium). --- Ion Ionisation stage (1=neutral) --- Left a left bracket ([) for predicted wavelength number=1 a wavelength is enclosed in brackets (indicating that a theoretical value of either or both energy levels of the transition has been used to derive the predicted wavelength; [Moore 1967] in the multiplet table). --- lambda Wavelength of the transition (in vacuum for lambda<2000A, in air for lambda>2000A) 0.1nm Right []] a right bracket (]) number=1 a wavelength is enclosed in brackets (indicating that a theoretical value of either or both energy levels of the transition has been used to derive the predicted wavelength; [Moore 1967] in the multiplet table). --- n_lambda See Note number=2 'a' Observed members of series shifted to longer waves by 0.309 A to 0.052 A (n - 5 to 8) when autoionization is effective. 'D' Line deleted in a later publication. 'I' Denotes intersystem combinations of astrophysical interest (see Moore 1965, p. VII for further remarks). 'm' Indicates that the line is masked. The spectrum of the masked line then appears in the intensity column with element identified in bytes 21-22 and atomic species number in byte 26. '*' The line is blended throughout and has more than one classification in the same spectrum (as opposed to appearance in intensity field, byte 23; see explanation for bytes 20-33). '?' for uncertain wavelength --- Ref Reference for the original analysis number=3 The references (letters A to K) are too extensive to be listed in this document and the source publications will need to be consulted if they are required. Users are advised to check the quality of each analysis from which the tables are assembled if uncertainties in identifications are encountered. The same letter codes denote different references in different sections, so the correct section must be consulted. The code "P" indicates a predicted wavelength. --- Int Line intensity number=4 various parts of this data field are uniform, e.g., it is possible to read the numerical intensities if the field is read with format (A3,F6.1,A5) since character data are in all cases separate from numerical intensities. Note, however, that a numerical intensity may be zero or blank, atomic species number may occur in a numerical field if an element is specified in bytes 21-22, and parentheses and asterisks are used to indicate intensity scale changes and that the intensity is affected by that of a neighbouring line or an impurity line. Thus, although numerical intensities may be read and tested upon, the overall data field must be considered for correct interpretation. --- E1 Lower excitation potential number=5 All limits and energy levels given in cm-1 have been multiplied by the factor 0.000123981 to obtain the respective values in eV (see Moore 1965). eV E2 Higher excitation potential number=5 All limits and energy levels given in cm-1 have been multiplied by the factor 0.000123981 to obtain the respective values in eV (see Moore 1965). eV J1 Lower J quantum number --- J2 H1gher J quantum number --- u_J2 A query (?) if the J values are uncertain (appears in source multiplet tables). --- UV "UV" if an ultraviolet multiplet number=6 The letters "UV" when a multiplet occurs shortward of 3000 A and blank for multiplets longward of 3000 A (stated in Moore 1965); however, multiplets having lambda < 3000 A occur throughout the sections without the UV prefix. --- Mult Multiplet number number=7 Due to the retention of earlier numbers from the RMT and UMT, a dual numbering system consisting of real and integer numbers is used (see Moore 1965, p. VII for a more detailed explanation); however, the integer numbers are aligned so that the F format can be used to read them as real numbers. Newly inserted numbers appear in decimal form, while integer numbers only are used after the old multiplet numbers are exhausted. --- Fflag denotes a forbidden transition. --- Blend See Note number=8 A code to indicate blends of specific lines, ultimate lines, italicized numerical intensities, as follows: ------------------------------------------------------------------ A Blended with Ar I C Expanded from single line in multiplet table (multiple J values) D Blend of Si III and Si IV E Blend of N III and N IV G Blend of C I and C II H Blend of C II and C III I Blend of C III and C IV J Blend of C IV and C V K Blend of N IV and N V L Blend of O IV and Si III M Blend of O IV and O V N Blend of O III and O V O Blend of O II and O V P Blend of O VI and O VII Q Blend of O VI and Be III R Blend of O III and O IV S Blend of O II and O IV U Ultimate line (raie ultime) W Blend of N III and N VI X Blend with N II Y Blend with O III Z Blend with Al II 1 Intensity given in italics (significance not found defined in publications) 2 1 + C ------------------------------------------------------------------ --- Sec Section number of HSRDS-NBS 3 publication --- Seq Sequential number of the line in the respective multiplet table. The original tables can be reconstructed by sorting the complete list by Sec,Seq --- Francois Ochsenbein CDS 1995Aug30 UNKNOWN UNKNOWN * December 1984, at ADC/NSSDC, by Wayne H. Warren Jr.: Sections 1-7 of the finding list (Adelman, Adelman and Fischel 1977) were available on magnetic tape. The multiplet tables of sections 8-10 were transcribed to data sheets at The Citadel by CJA and SJA, and transferred to disk storage at the ADC by WHW. A format was then designed to accommodate the data of all sections and the differing formats of both groups were changed to the new format. The individual sections were then broken out of the groups for checking. Corrections were made and detailed checks of the original publications performed, the format being revised several times to allow for additional information and to effect homogeneity in the data presentation. Groups of lines which had been added in Sections 1-7 without resequencing were moved to their correct locations and all sections were resequenced to be certain that a sequence sort will recover the original tables exactly. The individual sections were then combined and the complete file sorted by wavelength with secondary sorting on sequence number. * 30-Aug-1995: the printed documentation was converted into an electronic file at CDS. Problems which already occured in Catalogue VI/11 (Sections 1-7) have been corrected in records 4228, 5148, 6957, 7467, and 9951. VI_29A.xml
