Data, model and residuals for ring n = 543 of the LPC camera during the 2016-10-A baseline. For clarity only the night of 2016-10-08 is shown and the median of the residual rows has been subtracted from all panels, removing small normalization differences due to keeping the m_i fixed. Panel a: photometric time-series for the stars in ring n = 453 during the night of 2016-10-08 as a function of the hour angle after subtracting the mean magnitude m_i and cloud corrections (c_qt). Panel b: the transmission corrections T_nk obtained from solving Eq. (2). Panel c: the residuals after subtracting the transmission corrections. Panel d: the intrapixel corrections f(x_it, y_it) obtained from solving Eq. (2). Panel e: the residuals after subtracting the intrapixel corrections.
