- Error bars: Vertical (e.g., ±0.05 at redshift 1)
- **This work (dust-obscured)** (Red circles):
- Redshifts: 2, 3, 4, 5, 6
- Error bars: Vertical (e.g., ±0.03 at redshift 2)
- **This work (total)** (Black circles):
- Redshifts: 2, 3, 4, 5, 6
- Error bars: Vertical (e.g., ±0.02 at redshift 2)
## Key Trends and Observations
1. **Madau & Dickinson (2014) (Dashed Black Line)**
- Peaks at redshift ~2.5, then declines.
- Represents total SFRD.
2. **Zavala et al. (2021) (Shaded Areas)**
- `total` (Gray): Peaks at redshift ~2, declines afterward.
- `dust-obscured` (Orange): Peaks at redshift ~1.5, declines.
3. **Bouwens et al. (2021) (Crosshatched Areas)**
- `total` (Gray): Peaks at redshift ~3, declines.
- `dust-obscured` (Yellow): Peaks at redshift ~2.5, declines.
4. **This work (Red Line: Dust-Obscured)**
- Increases to redshift ~2, then decreases.
- Matches red data points (e.g., ~10⁻² at redshift 2).
5. **This work (Gray Line: Total)**
- Peaks at redshift ~1.5, then declines.
- Matches black data points (e.g., ~10⁻¹ at redshift 1.5).
6. **HST Dark Data (Green Stars)**
- Decreasing trend from redshift 1 (~10⁻³) to redshift 6 (~10⁻⁴).
## Annotations
- **HST dark**: Labeled near green stars.
- **This work (dust-obscured)**: Labeled near red line.
- **This work (total)**: Labeled near gray line.
## Spatial Grounding and Color Matching
- **Legend Colors**:
- Gray: Zavala total, Bouwens total, This work total.
- Orange: Zavala dust-obscured.
- Yellow: Bouwens dust-obscured.
- Red: This work dust-obscured.
- Black: This work total.
- **Data Point Colors**:
- Green stars (HST dark) match legend.
- Red circles (This work dust-obscured) match legend.
- Black circles (This work total) match legend.
