One needs to realize that the readout time, for each subframe is 10.5~$\mu$s if the detector is in parallel mode. 500~$\mu$s if the detector is in non parallel mode. Note that in {\tt{dr 32}}, as the single frame readout from the chip is 500~$\mu$s, no {\tt{subexptime}}$<$500~$\mu$s can be set in {\tt{parallel}} mode. To have smaller {\tt{subexptime}}, you need the {\tt{nonparallel}} mode, although this will have a larger deadtime than the acquisition time.\\
Online rate corrections can be activated for {\tt{dr=32, 16}}. They are particularly useful in the autosumming mode as every single subframe is corrected before summing it. To correct for rate, the subframe duration has to be known to the correction algorithm.

To activate the rate corrections, one should do:\\

\section{Load a noise pattern with shape}
For debug pourposes, we have created a noise pattern with a shape. If you reconstruct correctly your image, you should be able to read ".EIGER'' in the same direction for both the top and bottom in normal human readable orientation.
To load the special noise file copy the file {\tt{settingsdir/eiger/standard/eigernoise.sn048}} for every beb serial number snxxx you have and:
\begin{verbatim}
sls_detector_put trimbits ../settingsdir/eiger/standard/eigernoise
sls_detector_put vthreshold 4000
sls_detector_put vtr 4000
