+- `image`: The relative path to the original or manipulated image.  
+- `text`: The original or manipulated text caption.  
+- `fake_cls`: Indicates the type of manipulation (e.g., forgery, editing).  
+- `fake_image_box`: The bounding box coordinates of the manipulated region in the image.  
+- `fake_text_pos`: A list of indices specifying the positions of manipulated tokens within the `text` string.  
+- `cap_texts`: Textual information extracted from CAP (Contextual Auxiliary Prompt) annotations.  
+- `cap_images`: Relative paths to visual information from CAP annotations.  
+- `idx_cap_texts`: A binary array where the i-th element indicates whether the i-th celebrity in `cap_texts` is tampered (1 = tampered, 0 = not tampered).  
+- `idx_cap_images`: A binary array where the i-th element indicates whether the i-th celebrity in `cap_images` is tampered (1 = tampered, 0 = not tampered).
