| 説明 | This plot shows the data from the skysensor device measuring the all sky brightness in the range from full daylight to deep-sky. The local time runs from left to right, the day from bottom to top. Black points represent datagaps. You might notice the sinusodial shape, which can be explained by the equation of time. Midnight is on the left, noon is in the middle of this plot. The data from January and February seems to be darker, this could have been caused by snow-coverage of the sensor. |
