This technical report introduces ICHNOS, a Python-based quick-look web application designed to visualize both single spectra (obtained in position switching and nodding modes) and spatial distributions (continuum and spectroscopic maps) acquired at the Sardinia Radio Telescope using different receiver–backend combinations. After introducing the motivations behind this work, the report presents a technical overview of the software, highlighting its asynchronous architecture and its ability to handle real-time data streaming for different acquisition modes. This is followed by a detailed description of the graphical user interface and its interactive plotting capabilities. A test session aimed at evaluating the performance of the quick-look system with large datasets collected by the Sardinia Radio Telescope is finally presented, demonstrating the system’s efficiency in realistic operational scenarios.
