Welcome to VALD |

Extract element This request must have the following format begin request extract element [long format] [short format] <wavelength 1>,<wavelength 2> <element> [spectral number] end requestwhere <wavelength 1>,<wavelength 2> are again the limits of the spectral interval in Angstroem. Only the lines formed by <element> in one or all ionization stages will be extracted. [spectral number] defines the ionization stage: 1 stands for neutral atoms, 2 for singly ionized, etc. Currently VALD includes mostly lines up to the spectral number 5. If [spectral number] is omitted, the extraction is done for lines up to the four times ionized atom. Example begin request # Start of the request extract element # Request type 5700, 5720 # Wavelength range in Angstroems Fe 3 # Extract all lines of doubly ionized iron end request # End of the requestreturns: reqextelm.txt The mail reply will look similar to the one above, except that only lines of doubly ionized iron are included and each transition is supplemented with term designation (short format). | |
