Photometric bias
WebSubtracting the companion flux leaves V1334 Cyg in marginal agreement with existing photometric-based P –L relations, indicating either an overall calibration bias or a signi ficant intrinsic dispersion at a few percent level. Our work also enabled us to determine the dynamical masses of both components, MM 1 = 4.288 0.133 (Cepheid) and MM

WebThis flux density has been increased from the 0.057 mJy corresponding to W1 = 16.83 to correct for the 0.19 mag photometric bias in this W1 magnitude, as described below and … WebHowever, most photometric stereo methods tend to ignore factors that are relevant in practical applications. The setup considered in this paper tackles photometric stereo reconstruction in the case of a specific near-field imaging. This means that both the camera and the light sources are close to the imaged object, where close can be loosely ...
