Abstract:
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, 2000, Cat. J/A+A/383/188, 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 A(λ)/A(V)
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.
(1989ApJ...345..245C 1989ApJ...345..245C) a(x) and b(x) coefficients, second order fits to
A(λ)/E(B-V) 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).
