                                    double minimumStep)

Parameters:

supportedNames - regular expression for supported AGI/CSSI space weather files names

loader - data loader

dataProvidersManager - provides access to auxiliary data files.

utc - UTC time scale

maxSlots - maximum number of independent cached time slots in the time-stamped cache

maxSpan - maximum duration span in seconds of one slot in the time-stamped cache

maxInterval - time interval above which a new slot is created in the time-stamped cache

minimumStep - overriding minimum step designed for non-homogeneous tabulated values. To be used for example when caching monthly tabulated values. May be null.
