sunpeek.core_methods.virtuals.radiation.use_delta_kt_prime(time_index)

Return whether GTI-DIRINT may use its time-series stability index.

pvlib’s GTI-DIRINT can use the stability index delta_kt_prime only for sufficiently regular time-series input. For very short or irregular data, this returns False so the radiation model can still run for virtual sensor calculations on small data windows.
