Welcome to setigen’s documentation!¶
setigen
is a Python library for generating and injecting artificial
narrow-band signals into radio requency data. setigen
interfaces
primarily with two types of data: spectrograms or dynamic spectra, saved in two-dimensional NumPy arrays or filterbank files (.fil
extension), and raw voltages (GUPPI RAW files). Both data formats are instrumental to Breakthrough Listen’s data collection and analysis pipelines.
setigen
allows the user to generate synthetic signals quickly in the
time-frequency domain in the form of data Frames. Furthermore, the user may inject these synthetic signals
into real observational data loaded from filterbank files. setigen
plays well with the blimpy
package.
The setigen.voltage
module enables the synthesis of GUPPI RAW files via synthetic real voltage “observations” and a software signal processing pipeline that implements a polyphase filterbank, mirroring actual BL hardware. The voltage module supports single and multi-antenna RAW files, and can be GPU accelerated via CuPy.
