How to calculate the irradiance value of sunshine sensor?


#1

Dear all,
I have read all in this forum and I am still confused for this question.
@domenzain you said Sequoia is designed for measuring the reflectance value rather than the irradiance, but in the files of converting irradiance to reflectance, you pointed the key point is to getting the K, which means the ratio of the irradance of sunshine sensor and the irradiance of sequoia sensor can be calculated by the tags in the exif, so I want to know how to get the precise value of the irradiance of sunshine sensor, now I have known how to calculate the irradiance value of sequoia sensor.

Please directly give me the solution rather than give me another links. Thanks very much!
