FcaBedrock is a tool for creating context files for Formal Concept Analysis. It can convert existing data sets in flat-file CSV or 3-column CSV, to Burmeister (.cxt) or FIMI (.dat) context files. Release status: FcaBedrock v2.9.999, released 5 July 2026, is the final planned release of the legacy v2 line, and the first published release since v2.8.28 on 12 June 2014. No further v2 update is planned. The legacy tool will be superseded by FcaBedrock vNext, which is under development and...

`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.

rx2fits is an SDR code for the rx888mk2 direct-sampling receiver that streams spectral data with frequency up to 65 MHz to FITS files. 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. ...
