Description

Bremsstrahlung X-ray spectra each made of 30 raw enery channels. Each record is
a 10ms accumulation. The energy levels for bins in each record are tracked in
the 'energy' support data variable. NOTE: Unlike other BARREL products, these
data are not filtered by altitude (i.e. data below 25km are not removed).
Altitude should be checked in the EPHM file for the time period you are
interested in before use.

Description

Bremsstrahlung X-ray spectra each made of 30 raw enery channels. Each record is
a 10ms accumulation. The energy levels for bins in each record are tracked in
the 'energy' support data variable. NOTE: Unlike other BARREL products, these
data are not filtered by altitude (i.e. data below 25km are not removed).
Altitude should be checked in the EPHM file for the time period you are
interested in before use.

Description

Bremsstrahlung X-ray spectra each made of 30 raw enery channels. Each record is
a 10ms accumulation. The energy levels for bins in each record are tracked in
the 'energy' support data variable. NOTE: Unlike other BARREL products, these
data are not filtered by altitude (i.e. data below 25km are not removed).
Altitude should be checked in the EPHM file for the time period you are
interested in before use.
