A dataset containing wavelengths at a 1 nm interval (390 nm to 830 nm) and the corresponding response values for a 2 degrees target. Original data from http://www.cvrl.org/ downloaded on 2014-04-29 The variables are as follows:
Format
A chroma_spct object with 440 rows and 4 variables
An object of class response_mspct (inherits from generic_mspct, list) with 3 rows and 1 columns.
Value
A chroma_spct object.
A response_mspct object containing the same data in three
response_spct objects, one for each of x, y and z.
Note
These data are not from the official CIE on-line distribution but are retained for backwards compatibility. It is recommended to download the latest version from https://cie.co.at/data-tables.
The missing data for z in the NIR have been filled with zeros.
