Gain for each quadrant


Plotted line correspond to mean value
X-axis tics are plotted every 10th day





Read out noise for each quadrant


Plotted line correspond to mean value
X-axis tics are plotted every 10th day





Linearity limit (1%) for each quadrant


Plotted line corresponds to mean value
X-axis tics are plotted every 10th day





Linearity for each quadrant from newest data


Vertical line correspond to 1% non-linearity




Reset levels for each quadrant


Plotted green line corresponds to mean value
Blue (yellow) lines show max (min) values
X-axis tics are plotted every 10th day






Amount of zero pixels (%) and zero pixel map


X-axis tics are plotted every 10th day



Zero pixel map shows where zero pixels are in the latest data.



Full resolution dead pixel map




Amount of hot pixels (%)


Fraction of pixels that deviate more than 8-sigma from mean value.
Used exposure time was 36 seconds.
X-axis tics are plotted every 10th day





Amount of cold pixels (%)


Fraction of pixels that deviate more than 8-sigma from mean value.
Used exposure time was 36 seconds.
X-axis tics are plotted every 10th day





Temperature of the array


Mean temperature of the array during test.
Minimum and maximum temperatures during the test are indicated by the error bar.
