The KID is a relatively new and potentially game-changing superconducting detector technology which can provide photon noise
limited sensitivity over the entire mm-FIR wavelength range.
Poisson noise is also known as short or photon noise
In our case: [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is photon noise
signal, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is noise signal of current equal to photo diode one, and [U.
The error in the nightly measurements, primarily due to photon noise
, is about 0.
Furthermore, we can compute a theoretical error for this estimate, based on camera gain, readout noise and photon noise
