The corrected G passband is shown in Fig.1and listed in Table 1. The right panel of Fig.2assumes ZP G of 0, as that value is a priori unknown.

WebNote that if we are doing relative photometry-- measuring magnitude differences-- we do not need to worry about (3), and, under some circumstances, you can also ignore (2). In our experiment on globular cluster RR Lyraes we will be doing differential photometry and will not account for either (2) or (3), to keep things simple. 1. Background ... Webp passband, we adjusted the absolute flux levels of stars in the spectrophotometric libraries so that their synthetic H p magnitudes matched the precise Hipparcos Catalogue value. Synthetic photometry based on the renormalized fluxes was compared with the standard UBVRI, B T and V T magnitudes, and revised synthetic zero points were determined. http://srmastro.uvacreate.virginia.edu/astr313///////lectures/photometry/photometry_filters.html flagler county nursing homes
