 ### missing data check
-At the end of a point by point line, some data of asynchronous detectors may be missing.
-They are read until no more data is missing.
+At the end of a point by point line, some data of asynchronous detectors may be missing. Pixelator will wait and keep trying to read data from the asynchronous detector until either no more data is missing, or it has reached the maximum number of tries (i.e. **missingDataCheckMaxChecks**). The product of **missingDataCheckInterval** and **missingDataCheckMaxChecks** is the maximum time that Pixelator will wait before moving on to the next line of scan points.
