# Technical Data Extraction: Control Effect Analysis across Neural Network Layers
This document provides a detailed extraction of the data and trends presented in the provided image, which consists of two line graphs comparing "Explicit control" and "Implicit control" across different layers of a model.
## 1. General Metadata
* **Image Type:** Two-panel line chart with shaded error regions (confidence intervals).
* **X-Axis (Common):** "Layer" (Numerical values: 1, 8, 16, 24, 32).
* **Y-Axis (Common):** "Control effect (d)" (Numerical scale varies by panel).
* **Legend (Common):** Located in the top-left of each plot area.
* **Red Line:** LR
* **Blue Line:** Early PCs
* **Green Line:** Late PCs

## 2. Panel 1: Explicit control
**Spatial Grounding:** Left side of the image. Legend at approximately [x=0.15, y=0.15] relative to the panel.
### Data Series Analysis
| Series | Color | Visual Trend | Estimated Values (Layer 1 $\rightarrow$ 32) |
| :--- | :--- | :--- | :--- |
| **LR** | Red | Sharp upward slope until Layer 16, then a slight decline. | ~2.0, ~4.5, ~5.5, ~5.3, ~4.8 |
| **Early PCs** | Blue | Moderate upward slope until Layer 24, then a slight decline. | ~1.0, ~1.8, ~2.0, ~2.4, ~1.8 |
| **Late PCs** | Green | Relatively flat/stable near zero throughout all layers. | ~0.0, ~0.2, ~0.1, ~0.3, ~0.2 |
### Key Observations
* The "LR" series shows the highest control effect, peaking at Layer 16 with a value of approximately 5.5.
* The "Early PCs" series follows a similar trajectory but at a significantly lower magnitude (peaking around 2.4).
* "Late PCs" consistently show the lowest effect, remaining near the baseline of 0.

## 3. Panel 2: Implicit control
**Spatial Grounding:** Right side of the image. Legend at approximately [x=0.15, y=0.15] relative to the panel.
### Data Series Analysis
| Series | Color | Visual Trend | Estimated Values (Layer 1 $\rightarrow$ 32) |
| :--- | :--- | :--- | :--- |
| **LR** | Red | Flat at zero until Layer 8, then sharp increase peaking at Layer 24. | 0, 0, ~1.0, ~2.1, ~1.9 |
| **Early PCs** | Blue | Flat at zero until Layer 8, then moderate increase peaking at Layer 24. | 0, 0, ~0.5, ~0.7, ~0.6 |
| **Late PCs** | Green | Flat at zero until Layer 8, then very slight increase. | 0, 0, ~0.1, ~0.2, ~0.1 |
### Key Observations
* **Delayed Onset:** Unlike Explicit control, all series in Implicit control remain at 0 for the first 8 layers.
* The Y-axis scale is smaller (0 to 2+) compared to the Explicit control plot (0 to 6+).
* The "LR" series remains the dominant factor, peaking at Layer 24.
* There is a grey shaded rectangular region covering Layers 1 through 8 at the zero line, indicating a period of no effect or baseline measurement.

## 4. Comparative Summary
* **Magnitude:** Explicit control effects are roughly 2.5x to 3x stronger than Implicit control effects (comparing the peaks of the LR series).
* **Timing:** Explicit control effects are present from Layer 1, whereas Implicit control effects only emerge after Layer 8.
* **Consistency:** In both scenarios, the hierarchy of effect strength remains consistent: **LR > Early PCs > Late PCs**.
* **Peak Location:** Explicit control peaks earlier (Layer 16-24) compared to Implicit control, which shows a more distinct peak at Layer 24.
