Webphotometry the resulting passbands have a full-width half maximum (FWHM) ~ 100 nm (Majewski 2008). The sampling of a star’s spectrum by the passband is, however, a combination of the transmission of the filter and telescope optics, the response of the detector, and the transmission of the atmosphere as a function of wavelength. WebHow SPC works. SPC combines both stereo and photoclinometry techniques together to render an accurate topographical model. . . Stereo uses 2 images of the same terrain (in similar illumination conditions) where the spacecraft was in 2 close but different positions when the photograph was taken. Stereo then mathematically determines the distance ...
