Calculation of sky noise term #11

Closed iniyannatarajan closed 3 years ago

iniyannatarajan commented 6 years ago

Following up from @mjanssen2308's mail: we need an aperture efficiency parameter (most probable place to add this is the station_info.txt file) that modifies the DISH_DIAMETER column in the antenna table.

Another concern was that, for EHT, it might make more sense to use the receiver temperature instead of SEFD, since T_rx and the DPFUs are available - but not sure what the general community might prefer.

Not to self: Remove the 1/sqrt(2) prefactor in the add trop_noise function.

Incorporated aperture efficiency in dish area calculation and removed the 1/sqrt(@) prefactor in trop_add_sky_noise() in commit 80b70fac62cbedb50b79da50f5d50e2acdd3f081.

Still to resolve: Whether to use SEFD or T_rx as inputs.
