You can set the unique conditions for each group of elements for the performance of the database inquiry. The set of these conditions in Spectra Heap is named "Filter". Filters can be saved and used in your further work.
The filter consists of the following conditions:
- the choice of the tables "By Waves Lengths " or By Elements ";
- the range of waves lengths for their search (minimum and maximum value of line length);
- the choice of units of measurement (angstrems or nanometers);
- local filters (see below);
- the range of ionization;
- the conditions concerning line overlapping;
- the intensity value of arches or sparks in the table "By Waves Lengths";
- the range of excitation energy and the source of excitation in the table "By Elements".
