+Data Format
+================================
+
+Each UDP port creates its own output file, which contains the image data transmitted over that port. 
+
+Jungfrau
+-------------
+
+Single Port Configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. image:: images/Jungfrau_module.png
+   :width: 700px
+   :align: center
+   :alt: Jungfrau Module Single Port Configuration
+
+By default, only the outer 10GbE interface is enabled, transmitting the full image over a single UDP port. This results in one file per module containing the complete image.
+
+Total image size = 524,288 bytes 
+   - 8 chips (2 x 4 grid)
+   - 256 x 256 pixels (chip size)
+   - 2 bytes (pixel width)
+
+
+
+Double Port Configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. image:: images/Jungfrau_two_port.png
+   :width: 500px
+   :align: center
+   :alt: Jungfrau Module Two Port Configuration
+
+If both interfaces are enabled using the ``numinterfaces`` command on compatible hardware and firmware, the image splits into top and bottom halves sent over two UDP ports:
+
+   - The top half transmits via the inner interface (``udp_dstport2`` and ``udp_dstip2``).
+
+   - The bottom half uses the outer interface(``udp_dstport`` and ``udp_dstip``).
+
+The number of files per module equals the active UDP ports—two files per module when both interfaces are used.
+
+Image size per UDP port = 262,144 bytes
+    - **Complete Image size / 2**
+
+
+
+Special Cases
+^^^^^^^^^^^^^^
+
+.. image:: images/Jungfrau_read_rows.png
+   :width: 500px
+   :align: center
+   :alt: Jungfrau Module Read Partial Rows Configuration
+
+
+The number of image rows per port can be adjusted using the ``readnrows`` command. By default, 512 rows are read, but a smaller value centers the readout vertically (e.g., 8 rows reads 4 above and 4 below the center). Increasing the value symmetrically expands the region toward the top and bottom.
+
+
+Total image size = 32,768 bytes 
+   - 8 chips (2 x 4 grid)
+   - **8** x 256 pixels (chip size: **8 rows**)
+   - 2 bytes (pixel width)
