Query: BATSE Observations of Fast X-ray Transients Detected by BeppoSAX-WFC   The BeppoSAX Wide Field Cameras have been successful in detecting gamma-ray
bursts in the 2--26 keV energy range. While most detected bursts are also
strong emitters at higher energies, a significant fraction have anomalously low
gamma-ray flux. The nature of these "Fast X-ray Transients" (FXTs), and their
relation to gamma-ray bursts (GRBs), is unknown. We use BATSE untriggered
continuous data to examine the >20 keV gamma-ray properties of the events
detected in common with BeppoSAX. Temporal and spectral characteristics, such
as peak flux, fluence, duration, and spectrum are compared to the full
population of triggered BATSE GRBs. We find that FXTs have softer spectra than
most triggered bursts, but that they are consistent with the extrapolated
hardness expected for low-intensity GRBs.
