The SDSS ugriz filter transmission functions include the effects of whole optical system of the SDSS 2.5-m telescope and extinction through an air mass of 1.3 at Apache Point Observatory where SDSS has the SDSS 2.5-m telescope (see SDSS: Camera).
The u'g'r'i'z' Standard Star System -- USNO40 Response Function
The u'g'r'i'z' filters used on the USNO 40-in telescope at Flagstaff Station, Arizona, were manufactured by Asahi Spectra Co. Ltd. in Japan according to the specifications given at this URL. Here, we present the tabulated transmission curves for each filter, which were measured in 1995 by the SDSS Japan Participation Group (JPG) : u' g' r' i'

Dec 19, 2007 · We briefly discuss the history of the star selection process, the derivation of a set of transformation equations for the UBVRCIC system, and plans for future work. The linearity curve for the...
The u'g'r'i'z' Standard Star System -- Main - Fermilab
Sep 10, 2012 · Machine readable tables of their u'g'r'i'z' magnitudes and colors and of their astrometric and spectral properties are available from the electronic edition. The u'g'r'i'z' Standard Star System covers the Northern and Equatorial Regions.
SDSS Filters - Sloan Digital Sky Survey
Each filter is designed to let in light around a specific wavelength. The filters work by blocking out light at all wavelengths except those around the wavelength they are designed to see. The table to the right shows the wavelengths at which SDSS's five filters work the best.
Magnitudes are defined relative to some standard flux or object. In other words, for small uncertainties the uncertainty in magnitudes is the fractional uncertainty in flux. In other words, the fractional uncertainty in distance is about half the uncertainty in the distance modulus.
We describe a standard star catalog constructed using multiple SDSS photometric observations (at least four per band, with a median of ten) in the ugriz system. The catalog includes 1.01 million non-variable unresolved objects from the equatorial stripe 82 (|δJ2000| < …
Synthesized UBVRI-ZY and ugriz zeropoints are presented, calibrated on 20 calspec standards with standard photometry and covering a wide range of color, from DA white dwarfs through G/K stars to VB8 (M7V).
The CFHTLS ugriz filter set - UVic.ca
The figure at right shows the final CFHTLS filter transmission functions. The same data for the SDSS ugriz filter set is shown in heavier lines . Note the CFHTLS u and g filters are slightly redder than their SDSS counterparts.
