 ### Class Mapping
 
-- **Class 1**: Control diet methane plumes (166-171 ppm)
-- **Class 2**: Low forage diet methane plumes (300-334 ppm)  
-- **Class 3**: High forage diet methane plumes (457-510 ppm)
+- **Class 0**: Background
+- **Class 1**: Control diet methane plumes (166-171 ppm, 50:50 F:C ratio)
+- **Class 2**: Low forage diet methane plumes (300-334 ppm, 20:80 F:C ratio)  
+- **Class 3**: High forage diet methane plumes (457-510 ppm, 80:20 F:C ratio)
 
 **Mask Pixel Values:**
-- Pixel value 0: Background
-- Pixel value 1: Class 1 (Control diet, 166-171 ppm)
-- Pixel value 3: Class 2 (Low forage diet, 300-334 ppm)  
-- Pixel value 2: Class 3 (High forage diet, 457-510 ppm)
+> ⚠️ **Important**: There is a discrepancy between pixel values and class IDs in the mask files:
+
+- Pixel value 0: Background (Class 0)
+- Pixel value 1: Control diet (Class 1)
+- Pixel value 2: **High forage diet (Class 3)** ⚠️
+- Pixel value 3: **Low forage diet (Class 2)** ⚠️
