Lines GUI

Note: This page is a work in progress.

The standalone SNID-SAGE Line Manager is launched with snid-sage-lines.

This utility is separate from the main GUI's Spectral Lines button:

  • Spectral Lines is the in-app, post-analysis line-identification and line-analysis workflow
  • snid-sage-lines is a separate utility for managing line definitions, presets, and preview overlays

This standalone Line Manager is still evolving, so expect this page and the utility itself to change.

Purpose

Use the Line Manager to maintain the line database and presets that can later appear in spectral-line overlays.

Tabs

Tab Purpose
Lines Searchable table of effective lines (built-in + user)
Presets Define criteria sets (category, origin, SN types, strength, phase, name patterns)

Lines panel

Action Details
Manage lines Add/Edit/Delete user lines
Columns Name, Air/Vac wavelengths, Category, Origin, SN Types
Styling Bold rows = user-defined entries

Test Spectrum

  • Load a spectrum and preview with line overlays (pyqtgraph)
  • Toggle “in-range only” to limit overlays to visible wavelength range
  • Open Advanced Preprocessing for spectrum cleanup before checking overlays

Presets panel

  • Create and save named preset filters
  • Useful to focus on e.g. He I for Type Ib or H-alpha for Type II

Tips

  • Keep names consistent; include notes when adding new lines
  • Use presets to streamline repeated analysis tasks
