Table 4:

Main raw data for the two programmes with time sampling.
Variable Programme Sampling (s) Comment
Mean offset AS 1 Averaged on 1024 pixels, ( $\rm {ADU~px^{-1}}$)
Bright pixel number AS 1 Number of pixels brighter than $n\sigma$
Offset variance AS 1 Readout noise, ( $\rm {ADU~px^{-1}}$)
Star Intensity AS 1 Total inside the aperture, (ADU)
Baricentre X AS 1 star X position, (px)
Baricentre Y AS 1 star Y position, (px)
Background Intensity AS 1 Pixels brighter than $n\sigma$ are not included in the mean, $\rm {ADU~px^{-1}}$
Bright pixel number in background window AS 1 Number of pixels brighter than $n\sigma$
Offset PF 32 mean offset, $\rm {ADU~px^{-1}}$
Background PF 32 and 512 mean background, $\rm {ADU~px^{-1}}$
Star white flux PF 32 and 512 star total intensity in the aperture, $\rm {ADU}$
Star ``red'' flux PF 32 and 512 star total intensity in the red part of the aperture, $\rm {ADU}$
Star ``green'' flux PF 32 and 512 star total intensity in the green part of the aperture, $\rm {ADU}$
Star ``blue'' flux PF 32 and 512 star total intensity in the blue part of the aperture, $\rm {ADU}$

Note: on the AS channel the offset and background are subtracted on board.
