NORVIS Suite
The NORVIS software environment covers instrument control, data acquisition, spectral reduction and visualization. The same software framework is used for the different NORVIS units.
Acquisition and processing chain
Each NORVIS unit uses the same acquisition framework and data organisation. Observations can then be processed with the NORVIS reduction software using calibration information associated with the individual instrument.
NORVIS software architecture for instrument control, data acquisition, reduction and visualization.
NORVIS Control
Instrument control and acquisition
NORVIS Control is the interface used to operate the instrument during observations. It provides access to the science, slit-context and wide-field cameras together with their acquisition parameters and status information.
The science frames can also be converted into a one-dimensional spectral preview during acquisition, providing an immediate check of the recorded signal and spectral features.
Observation sessions and camera acquisition.
Exposure, gain and detector parameters.
One-dimensional spectrum generated during acquisition.
Wide-field and slit-context camera streams.
NORVIS Redux
Common spectral reduction
NORVIS Redux processes observations obtained by the different NORVIS units using a common reduction sequence. Calibration parameters specific to each instrument are retained and applied during processing.
The resulting products include reduced one-dimensional spectra and the associated metadata required to compare measurements obtained at different observing sites.
Observations and metadata
Spectral measurements, context images, acquisition parameters and calibration information are stored together within the NORVIS data structure. This provides a consistent description of observations acquired by different instruments.
Raw measurements
Science frames, slit-context images and wide-field images acquired during an observing session.
Acquisition information
UTC time, observing site, instrument configuration, exposure and detector settings.
Reduced spectra
One-dimensional spectra and associated products generated by NORVIS Redux.
NORVIS Viewer
Spectra and context images
NORVIS Viewer is a standalone application for displaying reduced spectra together with their corresponding context images and acquisition information.
The application and example observations are available from the NORVIS Data page.
