Notes. Each image consists of the number of exposures given in Col. 6 times the individual integration time given in Col. 5.

^(a)

Data taken in cube mode, so each image is a cube of the number of planes given in Col. 6, each having the individual integration time given in Col. 5.

^(b)

Differential image motion monitor (DIMM) seeing average of all images taken from the individual fits headers.

^(c)

Coherence time of atmospheric fluctuations.
