Types of request VALD-EMS currently supports 4 types of requests

show line extracts all information, available in VALD, about a specific spectral line (or rather, the same species) in a small wavelength window (several spectral lines from the same species could appear in the output).
extract all extracts best atomic parameters for all spectral lines in a given spectral window.
extract element extracts best atomic parameters for all spectral lines of the particular chemical element or ion in a given spectral window.
extract stellar extracts all spectral lines (with their best parameters), which produce significant absorption in a stellar atmosphere with given effective temperature and gravity.

The type of the request is indicated by one of the keywords, listed above, placed in the second line of the request. The content of the request depends on its type as described in the following sections. Compulsory parameters are inclosed in angle brackets <...> while optional parameters are put in square brackets [...].
