ska_ost_senscalc.mid.sefd

This module contains classes and methods for use in the SKA MID Sensitivity Calculator.

ska_ost_senscalc.mid.sefd.SEFD_antenna(Tsys, effective_dish_area)[source]

Method to calculate the system equivalent flux density of an antenna

Parameters:

  • Tsys (astropy.units.Quantity) – the system temperature for the dish

  • effective_dish_area (astropy.units.Quantity) – product of dish area and dish efficiency

Returns:

the SEFD of the dish

Return type:

astropy.units.Quantity

ska_ost_senscalc.mid.sefd.SEFD_array(n_type1, n_type2, sefd_dish_type1, sefd_dish_type2)[source]

Function to compute the system equivalent flux density of an heterogeneous array composed of two dish types.

Parameters:

  • n_type1 (int) – the number of dishes of type 1

  • n_type2 (int) – the number of dishes of type 2

  • sefd_dish_type1 (astropy.units.Quantity) – the dish SEFD for type 1

  • sefd_dish_type2 (astropy.units.Quantity) – the dish SEFD for type 2

Returns:

the SEFD of the array

Return type:

astropy.units.Quantity
