Dead pixels map

The DeadPixelsMap tool allows the creation of dead pixels maps that can be used in ExoSim.

The tool requires the number of dead pixels in the channel to distribute them randomly over the focal plane.

The following configuration are to be set into the tool input parameters

<channel> channel_name
    <detector>
        <dp_mean > 10 </dp_mean>
    </detector>
</channel>

Then the tool can be run as

import exosim.tools as tools

tools.DeadPixelsMap(options_file='tools_input_example.xml',
                           output='data/payload')

And it produces a .csv file for each channel with the coordinates of the dead pixels.

The result will be like

The tool can also be used in the case the exact number of the dead pixel is not known. In this case the inputs should include the uncertainty on this number.

<channel> channel_name
    <detector>
        <dp_mean > 10 </dp_mean>
        <dp_sigma > 1 </dp_sigma>
    </detector>
</channel>

The code will then select a random number of dead pixels centered in the dp_meam value and normally distributed with dp_sigma standard deviation.

The produced .csv files can be used as input for ApplyDeadPixelsMap, described in Dead pixels map.
