Temperature dependent radiometric responsivity of the MASI Mastcam-Z simulator. Radiometric coefficient variability was determined to be linear with temperature in the $-{35}^{\circ }$ C to $+{25}^{\circ }$ C range expected on Mars. Here we compare the single temperature measurements of the Mastcam-Z flight units (black points) to a more complete data set taken with the MASI. Six of the most representative filters are shown. Panel (a) shows the red, green, and blue pixel ratios for the broadband filters L0/R0, (b) for L2 for which only the red pixels are illuminated, (c) for L6 for which only the blue pixels are illuminated, (d) for the 800 nm L1/R1, (e) for R5, and (f) for the R6 broadband infrared filter with the greatest effect
