Simulated image and its components (Sect. 2.1).
(a) Straight filament with the profile displayed in Fig. 2, normalized to
. (b)
Identical Gaussian sources with an intrinsic FWHM size of 24′′,
convolved to 18′′ resolution and normalized to
IP = 100. (c) Isotropic Gaussian background
with a size of 4000′′ (FWHM), normalized to
IP,b = 10. (d) Random
instrumental noise with σnoise = 1.25. (e)
Full simulated image ℐλO
(≡ℐλD) with S/N = 80 and resolution
of 18′′. Three horizontal lines indicate the locations and direction of the
profiles shown in Fig. 2. Each panel’s dimensions
are 600 × 2820 pixels (), pixel size Δ = 2″.
