Dust extinction curves: Draine R_V=4.0 model

This dataset is based on the models described in Benson (2018).

Dust Properties

Dust grain properties are taken from Draine (2003) - specifically their model with R_V=4.0.

Stellar Geometry

Galactic disks follow exponential profiles in the radial direction, and sech² distributions in the vertical direction. The vertical scale height is set to a multiple, h_d, of the stellar disk scale length, and its value is encoded in each file name. Spheroids follow spherical Hernquist (1990) profiles.

Dust Geometry

Dust is distributed in the disk, and follows exponential profiles in both radial and vertical directions. The vertical scale height is set to a multiple, h_z, of the stellar disk scale length, and its value is encoded in each file name.
