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:

Usage

cone_fundamentals10.spct

cone_fundamentals10.mspct

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.

Details

  • w.length (nm)

  • x

  • y

  • 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.
