createIsoTempLinesTable: table of isotemperature lines for use with the Robertson Method

Description

createIsoTempLinesTable table of isotemperature lines for use with the Robertson Method (Robertson, 1968) to interpolate isotemperature lines from the CIE 1960 UCS.

Usage

createIsoTempLinesTable(SPD=NA,CIETable = get("ciexyz31", envir = environment()), 
TCS = get("TCSdata", envir = environment()))

Arguments

SPD

light source spd

CIETable

reference data values

TCS

spectral reflectance data of 14 color test samples for CRI

Value

Iso temperature lines table

# NOT RUN {
# illuminant A
SPD = illuminants[1:51*2-1,c('wlnm','A')] # every 10 nm
isoTempLinesTable <- createIsoTempLinesTable(SPD)
