Fig. 4From: Utilization of a meteorological satellite as a space telescope: the lunar mid-infrared spectrum as seen by Himawari-8The brightness temperature curves from HSD at bands 8–16. The gray dots show the brightness temperature in each pixel. The red points with error bars are the average values with standard deviations at every 0.5 H bin. The blue dashed lines indicate the noise level of AHI. The green dashed line in band 11 indicates the noise level of channel 5 of DivinerBack to article page
