Examplesofphotometryphotometry The physiological basis of heterochromatic flickerphotometrydemonstrated in the ganglion cells of the macaque retina. From theCambridge English Corpus The second method employs ultra-high precisionphotometryof the transits to detect the deviations caused by the presence of exoplanetary moons. From theCambridge English Corpus Given the methods used inphotometrythe absolute values could be in error by 0.2 log. From theCambridge English Corpus Isoluminance was determined for each stimulus using minimum flickerphotometry. From theCambridge English Corpus This definition is based on heterochromatic flickerphotometry. From theCambridge English Corpus Spectral efficiency measured by heterochromatic flickerphotometryis similar in human infants and adults. From theCambridge English Corpus Potassium was determined on a separate aliquot of the sample by flamephotometry. From theCambridge English Corpus As in classical flickerphotometry, one of these serves as reference light while the other is a test light. From theCambridge English Corpus Spectral absorbance and spatial distribution of macular pigment using heterochromatic flickerphotometry. From theCambridge English Corpus Isoluminance was determined for each axis and each subject using heterochromatic flickerphotometryfor a central circular 1-deg stimulus. From theCambridge English Corpus Maturation of visual pathways of heterochromatic flickerphotometrydemonstrated in the ganglion cells of the macaque retina. From theCambridge English Corpus Isoluminance was determined for a 1-deg circular field for every subject using flickerphotometry. From theCambridge English Corpus It is clear that these methods should be restricted to situations with moderately complexphotometrycombined with semantic complexity. From theCambridge English Corpus For that purpose, electroretinogram flickerphotometrywas used to obtain complete spectral sensitivity functions from 60 heterozygous female monkeys drawn from seven genera of platyrrhine monkeys. From theCambridge English Corpus Precisephotometrycould detect the transit signature of the moon in the transit profile of the massive planet.
