Peax™ is a fast and easy-to-use database software for searching, identifying and plotting elements and molecules in a spectrum. An easy to understand basic spectral viewer is included. 

 
Query cursor

Use the "Query cursor" function to view elements/molecules matching a wavelength selected by the cursor. The table view list, appearing in the Peax database view list, will automatically be updated as soon as on of its parameters is changed.
 

Query peaks

The "Query peaks" function works in a similar way as the "Query cursor" function, except that this function identifies multiple peaks, selected by the "peak picker" function.
 

Query range

Use the "Query range" function to display lines of elements or molecular bands not necessarily related to actual peaks or bands in the spectrum. The "Query range" function lists lines/bands from an element/molecule or a group of elements/molecules selected by the user, by for instance typing in the element symbols in the "elements" text field.
 

Table view list

The "Table view list" displays the element lines or molecules from the database, limited by the criteria given by either the "Query cursor", the "Query peaks" or the "Query range" functions. Using the below icons the user can filter, edit and plot records in the table view into the spectral viewer.

Settings

In the "Peax database settings" dialogue, general preferences can be set for the interaction of Peax with the database.

The settings parameters are:
- Database wavelength mode (air or vacuum)
- Elements settings
- Molecules settings 

Elements tab

In the "Elements tab" the user specifies all the atomic ionization stages to be included in the database search. The range of the ionization stage is from I (neutral atom) to XXVII (atom stripped of 26 electrons). The user can in addition filter out specific elements to be included in the queries to the database. The user can optionally save the filter settings for later use, through the "Save as" and the "Load" button.

The user can also specify optional element columns to be display in table view. These columns are:

Atomic number, Accuracy, Configurations, Line references, Observed wavelength, Vacuum wavelength, Ritz wavelength, Terms, Transition probabilities references, Type, A_ki, E_i - E_k, f_ik, g_i - g_k, J_i - J_k, log(gf), S

Molecule tab

In the "Molecules tab" the user specifies all the bands to be included in the database search. This settings dialogue works in a similar way as the "Elements tab".
