// Output Device Transform - P3D60
//

//
// Summary :
//  This transform is intended for mapping OCES onto a P3 digital cinema 
//  projector that is calibrated to a D60 white point at 48 cd/m^2. The assumed 
//  observer adapted white is D60, and the viewing environment is that of a dark //  theater. 
//
// Device Primaries : 
//  CIE 1931 chromaticities:  x         y         Y
//              Red:          0.68      0.32
//              Green:        0.265     0.69
//              Blue:         0.15      0.06
//              White:        0.32168   0.33767   48 cd/m^2
//
// Display EOTF :
//  Gamma: 2.6

// Assumed observer adapted white point:
