LOW Theoretical Background

The theoretical sensitivity is computed using direction, frequency, and LST-dependent SEFD values following the procedure described in Sokolowski et al. (2022). See the linked paper for more details.

Dynamic range warning

In addition to calculating the theoretical sensitivity, the LOW sensitivity calculator backend warns if it detects a bright (>10 Jy) off-axis source within the full width at half maximum (FWHM) of the LOW station beam calculated at the centre of the specified band. The backend uses a bright source catalogue derived from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey (Hurley-Walker et al. (2017)).
