| Description |
English: I made this in matlab (and screen captured it as a quick hack), from quantal data at http://www.cvrl.org/database/text/cones/smj2.htm. The black curve is a linear combination of the long and medium cone responses, and represents the photopic luminosity function. Probably other data sets are less lumpy.
Here's the code: % http://www.cvrl.org/database/text/cones/smj2.htm conelogQdata = [ ... 390, -3.0536, -3.1218, -1.8575 395, -2.6325, -2.6873, -1.4547 400, -2.3323, -2.3991, -1.1582 405, -2.0247, -2.0729, -0.8393 410, -1.7957, -1.8257, -0.6069 415, -1.6600, -1.6650, -0.4141 420, -1.5187, -1.4822, -0.2550 425, -1.4501, -1.3680, -0.1432 430, -1.3922, -1.2659, -0.0835 435, -1.3344, -1.1736, -0.0378 440, -1.2716, -1.0844, -0.0103 445, -1.2323, -1.0269, 0.0000 450, -1.1974, -0.9771, -0.0408 455, -1.1460, -0.9159, -0.0921 460, -1.0725, -0.8364, -0.1178 465, -0.9894, -0.7564, -0.1928 470, -0.9006, -0.6754, -0.2351 475, -0.8224, -0.6067, -0.3359 480, -0.7603, -0.5561, -0.4687 485, -0.7056, -0.5121, -0.6037 490, -0.6324, -0.4519, -0.7369 495, -0.5422, -0.3785, -0.8579 500, -0.4505, -0.3036, -0.9869 505, -0.3575, -0.2249, -1.1168 510, -0.2766, -0.1596, -1.2672 515, -0.2050, -0.1025, -1.4381 520, -0.1440, -0.0545, -1.6145 525, -0.0984, -0.0239, -1.8070 530, -0.0645, -0.0056, -1.9975 535, -0.0434, 0.0000, -2.1850 540, -0.0312, -0.0036, -2.3691 545, -0.0177, -0.0066, -2.5498 550, -0.0065, -0.0139, -2.7273 555, -0.0023, -0.0318, -2.9016 560, -0.0053, -0.0597, -3.0728 565, -0.0050, -0.0874, -3.2411 570, 0.0000, -0.1132, -3.4064 575, -0.0048, -0.1560, -3.5689 580, -0.0171, -0.2128, -3.7286 585, -0.0289, -0.2694, -3.8856 590, -0.0444, -0.3343, -4.0400 595, -0.0668, -0.4155, -4.1919 600, -0.0954, -0.5065, -4.3412 605, -0.1301, -0.6048, -4.4880 610, -0.1725, -0.7153, -4.6326 615, -0.2231, -0.8382, -4.7747 620, -0.2824, -0.9675, -4.9146 625, -0.3510, -1.1030, -5.0523 630, -0.4299, -1.2484, -5.1879 635, -0.5179, -1.4024, -5.3213 640, -0.6131, -1.5588, -5.4527 645, -0.7169, -1.7152, -5.5821 650, -0.8318, -1.8748, -5.7096 655, -0.9581, -2.0376, -5.8350 660, -1.0928, -2.2038, -5.9586 665, -1.2337, -2.3715, -6.0804 670, -1.3788, -2.5374, -6.2004 675, -1.5257, -2.6991, -6.3186 680, -1.6747, -2.8577, -6.4351 685, -1.8271, -3.0183, -6.5500 690, -1.9841, -3.1809, -6.6632 695, -2.1495, -3.3474, -6.7747 700, -2.3213, -3.5155, -6.8848 705, -2.4916, -3.6812, -6.9932 710, -2.6521, -3.8405, -7.1003 715, -2.8055, -3.9935, -7.2057 720, -2.9676, -4.1481, -7.3098 725, -3.1275, -4.3010, -7.4125 730, -3.2852, -4.4521, -7.5137 ]; lambda = conelogQdata(:,1); responses = 10.^conelogQdata(:,[2 3 4]); photopic = responses(:,[1 2]) * [0.68273; 0.35235]; figure(1); hold off plot(lambda, responses) hold on plot(lambda, photopic, 'k') hold offaxis([380 720 0 1.05]) |
