A set of small utilities to operate with BTA telescope

...This code is for the direct-sampling input of the receiver, which transmits real samples over USB3 at up to 130 MHz sample rate. rx2fits processes these samples to spectral intensities via a Fourier-transform poly-phase filter bank, which provides spectral resolution approaching the spectral bin width with good stop-band and adjacent-channel rejection. Sample rate, Fourier bin count, PFB frame count, integration time and receiver gain parameters can be set. Utilities for device enumeration, firmware upload, display of FITS header, file viewing, and for measuring sample rate and sample statistics are provided. The device interface is Ruslan Migirow's librx888 and dropped samples at 130 MHz are negligible. Runs on linux computers under .Net.

This linux package is a VLF receiver for monitoring VLF transmitter signals for evidence of transients indicating ionospheric disturbances. It takes sample pairs from dual-channel sound cards and spectrally processes them to Stokes parameters.

...It helps astronomers to perform an accurate astrometric reduction of dozens ore even hundreds of images which can be used in subsequent data analysis process. Fit headers generated by this software are fully compatible with other commonly used image utilities like SAO DS9 or Aladin Sky Atlas.
