Abundance¶
abundance_table
module-attribute
¶
Dataframe containing various abundances that can be used in jaxspec. It is adapted from
XSPEC's abundance table. The following table are available:
| Name | Reference | Note |
|---|---|---|
angr |
Anders & Gevresse (1989) | Photospheric, using Table 2. |
aspl |
Asplund et al. (2009) | Photospheric, using Table 1. |
feld |
Feldman (1992) | |
aneb |
Anders & Ebihara (1982) | |
grsa |
Grevesse & Sauval (1998) | |
wilm |
Wilms et al. (2000) | |
lodd |
Lodders (2003) | Photospheric, using Table 1. |
lgpp |
Lodders, Palme & Gail (2009) | Photospheric, using Table 4. |
lgps |
Lodders, Palme & Gail (2009) | Proto-solar, using Table 10. |
The table is a pandas.Dataframe object, and can be accessed as such. For example, to get the abundance of iron in the aspl table, one can do:
from jaxspec.util.abundance import abundance_table
assert abundance_table['Element'][ 26 - 1] == 'Fe'
print(abundance_table['aspl'][ 26 - 1]) # 3.16e-05
The full table is displayed below:
