Description: "tableE2.dat" -------------------------------------------------------------------------- This file comprises the abundance results for selected 8 stars derived from the Al I 6696 line. Note that the abundances from the weaker Al I 6698 lines (half as strong as Al I 6696) are essentially the same, and thus are not shown here. -------------------------------------------------------------------------- Byte-by-byte Description: "tableE2.dat" ----------------------------------------------------------------------------- Bytes Format Units Label Explanations ----------------------------------------------------------------------------- 1- 1 A1 --- caution_flag If "x", results may be unreliable (problems in obs.data) 3- 8 I6 --- HD HD number (Henry Draper Catalogue) 9- 14 I6 K Teff effective temperature 15- 19 F5.2 dex Logg log surface gravity (cgs unit) 20- 25 F6.2 dex [Fe/H] Fe abundance relative to Procyon 26- 30 F5.1 km/s xi microturbulence (derived by Teff-dependent relation) 31- 34 I4 km/s vsini projected rotational velocity 35- 41 F7.1 mA W6696 equivalent width of Al I 6696 42- 48 F7.3 dex AN6696 NLTE Al abundance for Al I 6696 49- 55 F7.3 dex AL6696 LTE Al abundance for Al I 6696 56- 62 F7.3 dex d6696 NLTE correction for Al I 6696 (= AN6696 - AL6696) 65- 65 A1 --- Source Key to the data used for the analysis of Al I 6696/6698 lines ----------------------------------------------------------------------------- Description: "tableE3.dat" -------------------------------------------------------------------------- This file comprises the abundance results for selected 6 stars derived from the Al II 3900 line. -------------------------------------------------------------------------- Byte-by-byte Description: "tableE3.dat" ----------------------------------------------------------------------------- Bytes Format Units Label Explanations ----------------------------------------------------------------------------- 1- 1 A1 --- caution_flag If "x", results may be unreliable (problems in obs.data) 3- 8 I6 --- HD HD number (Henry Draper Catalogue) 9- 14 I6 K Teff effective temperature 15- 19 F5.2 dex Logg log surface gravity (cgs unit) 20- 25 F6.2 dex [Fe/H] Fe abundance relative to Procyon 26- 30 F5.1 km/s xi microturbulence (derived by Teff-dependent relation) 31- 34 I4 km/s vsini projected rotational velocity 35- 41 F7.1 mA W3900 equivalent width of Al II 42- 48 F7.3 dex AN3900 NLTE Al abundance for Al II 3900 49- 55 F7.3 dex AL3900 LTE Al abundance for Al II 3900 56- 62 F7.3 dex d3900 NLTE correction for Al II 3900 (= AN3900 - AL3900) 65- 65 A1 --- Source Key to the data used for the analysis of Al II 3900 line ----------------------------------------------------------------------------- Description: "tableE4.dat" -------------------------------------------------------------------------- This file comprises the abundance results for selected 10 stars derived from the Al II 4663 line. -------------------------------------------------------------------------- Byte-by-byte Description: "tableE4.dat" ----------------------------------------------------------------------------- Bytes Format Units Label Explanations ----------------------------------------------------------------------------- 1- 1 A1 --- caution_flag If "x", results may be unreliable (problems in obs.data) 3- 8 I6 --- HD HD number (Henry Draper Catalogue) 9- 14 I6 K Teff effective temperature 15- 19 F5.2 dex Logg log surface gravity (cgs unit) 20- 25 F6.2 dex [Fe/H] Fe abundance relative to Procyon 26- 30 F5.1 km/s xi microturbulence (derived by Teff-dependent relation) 31- 34 I4 km/s vsini projected rotational velocity 35- 41 F7.1 mA W4663 equivalent width of Al II 4663 42- 48 F7.3 dex AN4663 NLTE Al abundance for Al II 4663 49- 55 F7.3 dex AL4663 LTE Al abundance for Al II 4663 56- 62 F7.3 dex d4663 NLTE correction for Al II 4663 (= AN4663 - AL4663) 65- 65 A1 --- Source Key to the data used for the analysis of Al II 4663 line ----------------------------------------------------------------------------- Description: "ncor???????.dat" -------------------------------------------------------------------------- The data contained in each of these data files are: lambda, xi, [Al/Fe] (=0.00), Ainput, W(LTE), W(NLTE), A(NLTE), A(LTE), delta and code, where lambda is the line wavelength. xi is the microturbulent velocity, and [Al/Fe]=0 was assumed for all calculations. The theoretical equivalent widths (LTE as well as NLTE) were evaluated for Ainput = 6.47 + [Fe/H] (6.47 is the solar alminum abundance) A(NLTE) and A(LTE) are the abundances derived from W(NLTE) under the assumption of NLTE and LTE, respectively. Though A(NLTE) should be equal to Ainput in the strict sense, there are practically small discrepancy because of numerical problems. The delta is the NLTE correction defined as delta = A(NLTE)-A(LTE). The code represents effective temperature, surface gravity, and metallicity: for example, t070g30m05 --> Teff=7000K log g=3.0 [X/H]=[Fe/H]=-0.5 t085g40m10 --> Teff=8500K log g=4.0 [X/H]=[Fe/H]=-1.0 t100g45p00 --> Teff=10000K log g=4.5 [X/H]=[Fe/H]= 0.0 t130g35p05 --> Teff=13000K log g=3.5 [X/H]=[Fe/H]=+0.5 -------------------------------------------------------------------------- Byte-by-byte Description: "ncor???????.dat" -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 9 F9.2 A wavelength wavelength of the line 10- 13 F4.1 km/s xi microturbulence 14- 18 F5.1 dex [Al/Fe] assigned alminum-to-iron logarithmic abundance ratio 19- 25 F7.3 dex Ainput assigned Al abundance (usual normalization of H=12.00) 29- 36 F8.2 mA W(LTE) LTE equivalent width 39- 46 F8.2 mA W(NLTE) NLTE equivalent width 47- 53 F7.3 dex A(NLTE) NLTE abundance 54- 60 F7.3 dex A(LTE) LTE abundance 61- 67 F7.3 dex Delta Non-LTE abundance correction 68- 75 F8.0 K Teff Effective temperature 76- 81 F6.2 dex Log g logarithmic surface gravity (in c.g.s) 84- 93 A10 --- code model code --------------------------------------------------------------------------------
