#' Intensity and saturation values of a picture from mars.
#'
#' A dataset containing the Intensity and Saturation values of a picture from Mars
#' taken from Rover Curiosity.
#' @format A list containing information about  pixels of a picture form mars mainly
#' containing red sand and  metal form Rover itself. List include:
#'
#' \itemize{
#' \item SI_matrix: A matrix with 5063 rows and 128 columns.
#' Elements 1 to 64 of each row indicate the Saturation values of pixels in a square cell 8 x 8
#' whereas elements 65 to 128 of each row indicate the cell's Intensity  values.
#' \item geographic_matrix: An integer matrix of dimension 5063 x 2, each row indicates
#'  each square cell's locations (x-axis y-axis) at the picture.
#'  \item screw_index: the index corresponding to the screw observation (screw_index=4180)
