Extract All

This request must have the following format

   begin request
   extract all
   [via ftp]
   [long format]
   [short format]
   <wavelength 1>,<wavelength 2>
   end request
where <wavelength 1>,<wavelength 2> are the limits of the spectral interval in Angstroems. Note that VALD limits the total number of lines per single mail to 1000, therefore the actual extraction may end somewhat shorter of <wavelength 2>. [via ftp] allows the extraction of more lines, but the data will not be sent via e-mail. It has to be downloaded within a certain time span. [long format] tells VALD to include an extra line of data with term designation, Lande factors, and accuracy description into the output file. [short format] does not include these data and is the default.

Example

   begin request          # Start of the request
   extract all            # Request type
   default configuration  # No special configuration
   short format           # Dislay each transition on only one line
   5700, 5701             # Wavelength range in Angstroems
   end request            # End of the request
As the result VALD will mail back to the client VALD-EMS request number, the copy of the request and a subset of spectral lines between 5700 and 5701 Angstroems as shown in the example reqextall.txt

Example using the 'via ftp' option.

   begin request          # Start of the request
   extract all            # Request type
   via ftp
   default configuration  # No special configuration
   short format           # Dislay each transition on only one line
   5700, 5701             # Wavelength range in Angstroems
   end request            # End of the request

The output columns contain element and ionization stage, central wavelength in Angstroem, excitation in electron--Volts, log(gf), 3 damping constants in logarithm (radiative, quadratic Stark and van der Waals) per sec and per perturber at 10000K (in the case of Stark and van der Waals constants), mean Lande factor and reference labels. Zero in place of a damping parameter and 99 in place of the Lande factor marks the absence of the corresponding data in VALD. The labels at the end of each line show the source of the respective output column. The SHOW LINE request may be used to find out all values of transition parameters from different VALD lists and their corresponding ranking, assigned by the VALD team.
