v2.0-beta

New Features

• Observation Mode — Full-featured observation data processing, analysis, and visualization with DSSD strip histograms (X1-X8, Y1-Y8) and BGO plots
• Unified Main Window — Office-style ribbon UI with tabs (Home, Data, Analysis, Config, Observation), replacing the Navigation Rail with a single-window layout
• Observation Detail View — Popup window with histogram plotting and curve fitting for individual channels
  Excel Export — Observation results exported to Excel via new ExcelHelper service
• Channel Management — Core channel management with baseline processing and thresholding

Curve Fitting Improvements

• Unified fitting — Observation view now uses the same MathService as Baseline, ensuring consistent Gaussian/Lorentzian results across both views

• FWHM, Resolution, R² — Gaussian fit now computes FWHM (
  2.355
  σ
  2.355σ), energy resolution, and R-squared statistics

• Fit method selection — ComboBox to switch between Gaussian and Lorentzian fitting, with live plot refresh on change

• Improved initial guess — CalculateWeightedMoments uses half-maximum peak detection instead of a hardcoded ±200 bin window

Graph & UI Enhancements

• Bar width fix — BarWidth set to actual bin width so histogram bars are visible (not just 1-pixel lines)
• Bar border color — Border matches fill color instead of default black
• Configurable graph background — Default changed from black to dark gray; user can customize via Settings
• Customizable bar colors — DSSD (orange default) and BGO (cyan default) colors changeable in Settings

Project Structure

• Restructured into Core / Infrastructure / Presentation layers
• Views organized into Baseline / Observation / Shared folders
• Status bar with progress indicator
