 * **Tactile Data:** Per-frame aligned glove sensor data stored in high-performance `.parquet` format.
 * **Calibration:** Intrinsic and extrinsic parameters provided in `.json`.
 
+### Coordinate Systems & Alignment
+To facilitate ease of use for 3D reconstruction and multimodal learning, the data alignment is defined as follows:
+
+* **RGB & Depth:** The Depth stream is **software-aligned** to the RGB camera coordinate frame. A pixel at (u, v) in the depth map corresponds directly to the pixel (u, v) in the RGB frame.
+* **Monochrome Stereo:** The Left and Right monochrome cameras operate in their **own independent coordinate frames**. 
+* **Resolution Note:** While RGB/Depth are 720p, the Monochrome streams are captured at 640x400 resolution.
