is a web-application to access astronomical data stored in FITS-files.
It implements SODA IVOA recommendation v1.0 (https://ivoa.net/documents/SODA/20170517/index.html).
Additionally to SODAv1 it also provides VLKB-specific functions:

- the filtering paramters (POS, BAND) can be given in GALACTIC and VELO-LSRK-km/s coordinates systems
- supports non-WCS cuts by pixels grid
- inserts additional metadata (RESTFREQ, CUNIT) if not present in FITS-headers
- can create and hold a cut-file server-side for later download, and
- provides count of undefined values in the cut-file


The service consists of

- **vlkb-soda** web-application and associated **vlkbd** daemon to access FITS file contents based on VO SODA
- **vlkb** command line utility to perform some of the functionalities of the web-applications on command line
