This file is used to schedule calling of the fidTrop program which computes zenith tropospheric delay values for all ground GPS (fiducial) stations.

For real time processing, the file is a perl snippet which contains a list of fiducial stations so far received. This file is updated whenever new fiducial data are received, and when the list grows large enough, the file is submitted to the scheduler to call fidTrop.

For post-processing, this file is automatically created, with zero size, for all time ranges for which fidTrop processing is necessary. In the post-processed case, it is assumed that all fiducial data are in place so this file is just used as a convenience for starting fidTrop processing.
