Support convolution over broadbands in imported source luminosity probe #155

Closed petercamps closed 2 years ago

petercamps commented 2 years ago

Description When associated with a form that parallel-projects the luminosity towards a distant observer, the imported source luminosity probe outputs a quantity that is equivalent to surface brightness. In other words, it can be used to produce transparent noise-free images of the imported sources in a simulation.

If the convolve user configuration property is false , the luminosity is sampled at the characteristic wavelength of each bin. This is the default and previously the only behavior. With this update, if the convolve property is true, the luminosity is averaged over the width of each wavelength bin (for disjoint wavelength grids) or convolved over each broadband transmission curve (for band wavelength grids).

Motivation This capability allows generating transparent images that exactly match the data cubes generated by the instruments, including the convolution over broadband filters where appropriate. This is useful, for example, to calculate attenuation maps by dividing the corresponding attenuated and transparent pixels.

Tests Functional tests were added.
