At daylight levels, the curves are approximately straight with slope 1, i.e. log = log +., implying = / is constant. At the very darkest background levels ( B {\displaystyle B} ≲ 10 − 5 cd m −2 , approximately 25 mag arcsec −2 ) [ 24 ] the curves are flat - this is where the only visual perception is the observer's own neural noise ...
