The Asiago Database on Photometric Systems (ADPS)

The Asiago Database on Photometric Systems (ADPS) is a compilation of basic information and reference data on 201 photometric systems (both ground-based and space-born), available in printed form (Moro & Munari [CITE], hereafter Paper I) and electronically (http://ulisse.pd.astro.it/ADPS). Seventeen new systems have been added to ADPS since its publication, bringing the total to 218. In this Paper II, band and reddening parameters are homogeneously computed via synthetic photometry for the censed photometric systems with known band transmission profiles (179 systems). Band parameters include various types of wavelengths (mean, peak, Gaussian, and effective according to a series of representative spectral types), widths (width at half maximum, at 80% and 10% of transmission's peak, FWHM of the fitting Gaussian, equivalent, and effective for representative spectral types), moment of the 2nd order, skewness and kurtosis indices, and polynomial expressions for the behavior of effective wavelength and effective width as function of black-body temperature. Reddening parameters include for three reddening laws (characterized by RV=5.0, 3.1 and 2.1) and its range of variability over the HR diagram, the Cardelli et al. ([CITE]) and coefficients, second order fits to for three representative spectral types, and polynomial expressions for the behavior of effective wavelength and effective width as function of reddening (for the RV=3.1 law).
