What is the difference between .ppm and .vicar?

Description: A PPM file is a 24-bit color image formatted using a text format. It stores each pixel with a number from 0 to 65536, which specifies the color of the pixel. PPM files also store the image height and width, whitespace data, and the maximum color value.; The VICAR (Video Image Communication And Retrieval) Image file format is a flexible, image-processing and data format system used primarily by the planetary science community. Developed by NASA's Jet Propulsion Laboratory (JPL) for storing and managing digital images from space missions, VICAR files are designed to support a wide range of image types, including scientific and engineering data from various spacecraft instruments. This format is characterized by its ability to handle multi-dimensional arrays of data.
