Data for spectral response for different types of broadband sensors are
stored as objects of class sensor_spct
as collection members in
an object of class sensor_mspct
.
In addition to the spectra the package provides character vectors of names
to be used as indexes to extract spectra from the collection.
Data for angular response for different types of broadband sensors and some
diffusers used as entrance optics for spectrometers are stored as objects
of class data.frame
as members of a list
.
In addition to the list of data frames, the package provides character vectors of names
to be used as indexes to extract the data frames from the named list.
The data in this package are not original. Some have been provided by
authors of scientific publications and manufacturers. However, most of
the spectra have been digitized from manufacturer's brochures and manuals
available on web sites.
