The radial velocity method is a very productive technique used to detect and confirm extrasolar planets. most recent spectrographs, such as ESPRESSO or EXPRES, have the potential Earth-like planets around Sun-like stars. However, stellar activity can induce variations that dilute even mimic signature of planet. A widely recognized for disentangling these signals model time series, jointly with ...

conclusions according to the factory noise map, except for the control rooms with 81 dba noise, other cases of measuring stations were higher than the standard exposure of 85 dba noise. as a result, the implementation of control strategies, such as inspection and performance of control systems and insulation of the control room to prevent unnecessary exposure noise, are necessary. background st...

In this paper, the performance of a Ring Laser Gyro based inertial navigation is investigated. Dynamic and stochastic modeling are applied to gyro simulation and performance evaluation. In the dynamic model, some parameters such as scale factor and environmental sensitivity have been determined, whereas in the stochastic model, the other parameters such as random drift and measurement noise...

We present a Bayesian method for estimating instrumental noise parameters and propagating uncertainties within the global BeyondPlanck Gibbs sampling framework, apply this to Planck Low Frequency Instrument (LFI) time-ordered data. Following previous literature, we initially adopt $1/f$ model power spectral density (PSD), but find need an additional lognormal component in 30 44\,GHz bands. impl...
