### Technical Document Extraction: System Log Data Table
This image displays a structured technical log, likely from a high-performance computing system (indicated by the "RAS KERNEL INFO" and hardware location strings). The image is segmented into two primary logical regions: **Header** (left, green border) and **Content** (right, blue border).
---
#### 1. Component Isolation
* **Header Region (Left):** Contains metadata including Unix timestamps, dates, hardware location identifiers, high-precision timestamps, and log source classification.
* **Content Region (Right):** Contains the specific error messages or status updates associated with the corresponding header entry.
* **Footer/Ellipses:** Both sections end with "..." indicating that this is a truncated sample of a larger dataset.

#### 2. Data Table Reconstruction
The following table reconstructs the textual information provided in the image. The data is organized into three distinct log entries.
| Entry | Header Data (Metadata & Timestamps) | Content (Log Message) |
| :--- | :--- | :--- |
| **1** | 1117838978 2005.06.03 R02-M1-N0-C:J12-U11 2005-06-03-15.49.38.026704 R02-M1-N0-C:J12-U11 RAS KERNEL INFO | instruction cache parity error corrected |
| **2** | 1117843015 2005.06.03 R21-M1-N6-C:J08-U11 2005-06-03-16.56.55.309974 R21-M1-N6-C:J08-U11 RAS KERNEL INFO | 141 double-hummer alignment exceptions |
| **3** | 1117848119 2005.06.03 R16-M1-N2-C:J17-U01 2005-06-03-18.21.59.871925 R16-M1-N2-C:J17-U01 RAS KERNEL INFO | CE sym 2, at 0x0b85eee0, mask 0x05 |
| **...** | ... | ... |

#### 3. Detailed Content Analysis
**Header Structure Breakdown:**
Each line in the Header follows a consistent pattern:
1. **Unix Epoch Timestamp:** (e.g., `1117838978`)
2. **Date (YYYY.MM.DD):** (e.g., `2005.06.03`)
3. **Hardware Location ID:** A string identifying the Rack, Module, Node, and Component (e.g., `R02-M1-N0-C:J12-U11`).
4. **Full ISO Timestamp:** (e.g., `2005-06-03-15.49.38.026704`)
5. **Redundant Location ID:** Repeats the hardware location string.
6. **Log Source:** `RAS KERNEL INFO` (Reliability, Availability, and Serviceability kernel information).
**Content/Message Analysis:**
* **Entry 1:** Reports a corrected hardware error related to the instruction cache parity.
* **Entry 2:** Reports a specific count (141) of "double-hummer alignment exceptions," which refers to a specific floating-point unit architecture (Double Hummer) used in IBM Blue Gene/L systems.
* **Entry 3:** Reports a Correctable Error (CE) at a specific memory address (`0x0b85eee0`) with a bitmask (`0x05`).

#### 4. Spatial and Trend Observations
* **Spatial Placement:** The "Header" label is centered at the top of the green box. The "Content" label is centered at the top of the blue box.
* **Temporal Trend:** The timestamps show a chronological progression throughout the day of June 3, 2005, starting at 15:49:38 and ending at 18:21:59.
* **Hardware Variation:** Each log entry originates from a different hardware component (R02, R21, and R16), suggesting these are system-wide logs rather than logs from a single node.
