`lms2fits` is a dual-channel spectroscopic receiver for radio astronomy that employs theLimeSDR's LimeSDR-USB dual-channel transceiver, which in turn employs Lime Microsystems' LMS7002M transceiver chip. These systems allow a frequency-agile (<30 MHz to 3.8 GHz) receiver providing Stokes parameters in dynamic spectra of up to 60 MHz analog bandwidth streamed to a FITS file with three-axis primary table. It runs on linux under .Net.
Features
- Fourier-transform-type spectral analysis for 100% data utilization; multiframe poly-phase filter bank.
- Output streamed to FITS file with comprehensive metadata.
- Utilities for device enumeration, measuring sample rate against the system clock, the measurement of sample statistics (mean and standard deviation), and for viewing the primary headers of FITS files.
- FITS file viewer in python that permits dividing out gain models and for background subtraction.
- Installer for dependencies and and system configuration.
