Determining Equivalent Perceived Brightness

[t***@hotmail.com]

How would I go about determining the equivalent perceived brightness
given that I have the CIE color coordinates x,y and luminance of the
sample that I want to match and the CIE color coordinates x,y of the
sample to be matched. For example: If I have the CIE coordinates .
703, .297 with a luminance of 2000 and I wanted to match the perceived
brightness of CIE coordinates .536, .445. What would the luminance of
this sample ( .536, .445) need to be to match the perceived brightness
of the referenced sample (.703, .297 with luminance of 2000)?
