|The task has failed to uniquely
identify the user-selected reference sources in a newly accumulated
image. The source cross-identification is based on a simple integrated
flux criterion which is known to be deficient. There is no real problem
as long as the sources in question are sufficiently spatially separated.
If this is not the case, the algorithm will not abort execution but
the user should see an oscillating behavior in .
