createIsoTempLinesTable function

table of isotemperature lines for use with the Robertson Method

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

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

Returns

Iso temperature lines table
