ShowLine request
ShowLine request format
ShowLine extraction tool is meant for understanding the how the data from multiple sources is merged into the output transition information. In VALD3 ShowLine request can be performed using the conventional email service (EMS) or as an interactive web-form query.
The format of an EMS request looks like this:
begin request Show Line <options> <lambda>, <wavelength_window> <species1>, ... … end request
The search will be performed in a wavelength_window around the selected wavelength lambda. Species name is optional. One can include ionization stage if only transitions for specific ion are needed. Multiple species (comma separated) can be listed in a single request. Species names are case-sensitive.
Here is an example of a ShowLine request:
begin request showline 4491.405, 0.1, Fe 1, Fe 2 end request
Options
Currently the only two supported options are:
Default configuration or Personal configuration
Isotopic scaling on or Isotopic scaling off
All other options for now are fixed as following:
Extended Waals
Energy unit eV
Medium air
Wave unit A
Output example for ShowLine
The output consist of two parts. First, all VALD3 data relevant for specified constraints are listed using long format. The second part shows the result(s) of the merger. SHOWLINE V.4.0
Extracts all information about one particular line
and possible replacements from VALD 3.0 files
and shows the results of the merger.
