\subsection{The FOCUS Averager}
|
|
This is a special object for the instrument FOCUS and its Status display
|
|
client. In the FOCUS status display the averaged data from a number of
|
|
detectors is displayed. Thus there is already a reduced form of data. The
|
|
actual raw data would be 150*1024*4 bytes of data and possibly more. Rather
|
|
then transporting all this data to the status display client at regular
|
|
intervalls it was choosen to implement this averaging process at the server
|
|
and only send the reduced form to the status display client. Which is two
|
|
arrays of floating point data 1024 items long. This little object implements this
|
|
averager.
|
|
|
|
As all SICS objects this object has a little data structure:
|
|
\begin{verbatim}
|
|
typedef struct __FocusAverager {
|
|
pObjectDescriptor pDes;
|
|
pHistMem pHist;
|
|
} FocusAverager;
|
|
\end{verbatim}
|
|
|
|
The two fields are the standard object descriptor and a pointer to the
|
|
histogram memory object holding the data.
|
|
|
|
The interface is minimal: it consists just of the factory function for
|
|
installing this object into SICS and the actual function doing the
|
|
averaging in the interpreter.
