I try to convert spectral data to status T density by function
"xsp_Tdensity", but the result is diffrent from what i get direct from
X_rite Dtp_41. Is there something wrong with the function "xsp_Tdensity"?
spectral data:
31 bands,from 400nm to 700nm
33.142, 36.972, 41.308, 42.932, 43.188, 42.707, 39.626, 34.012,
27.997, 24.171, 21.336, 18.993, 17.318, 16.641, 16.215, 15.717,
15.473, 15.164, 17.648, 25.237, 40.321, 58.473, 71.486, 78.814,
82.367, 84.754, 85.808, 85.980, 85.785, 85.985, 86.392

status T density
measured with X_rite Dtp_41 (VCMY)0.504, 0.264, 0.768, 0.453
Calculate by "xsp_Tdensity" (CMYV)0.242, 0.521, 0.423, 0.352
