A vector of indexes for extracting subsets of spectra from the
sensors.mspct object.
Details
Irradian sensors DA211A-Cos (UV-A), DA211B2-Cos (UV-B), DV211Q-Cos (PAR), DV211E-Cos (pyranometer).
Manufacturer: Irradian Ltd., Tranent, East Lothian, Scotalnd, U.K.
Note
Digitized with 'DigitizeIt' or 'engauge' from manufacturers publications. This are approximate data, both because of the digitizing process, and because they are either typical values or for a specific sensor unit. Individual sensor units are expected to differ to some degree in spectral response. In the case of multichannel sensors, the spectra for all channels are plotted in the same figure in the data sheets and in out-of-band regions the lines overlap making accurate extraction of values difficult. Variation from unit to unit affects both response and center/peak wavelengths.
