lc_noise | R Documentation |
Generates measurement accuracies, a white noise component depending on them and a second (possibly power law, i.e. red) noise component which does not depend on the measurement accuracies.
For more details see tsgen
or Thieler, Fried and Rathjens (2016).
See RobPer-package
for more information about light curves.
lc_noise(tt, sig, SNR, redpart, alpha = 1.5)
tt |
numeric vector: Observation times given. |
sig |
numeric vector of same length as |
SNR |
positive number: Defines the relation between signal and noise (see |
redpart |
numeric value in [0,1]: Proportion of the power law noise in noise components (see |
alpha |
numeric value: Power law index for the power law noise component (see |
y |
numeric vector: Observed values: signal + noise. |
s |
numeric vector: Measurement accuracies related to the white noise component. |
A former version of this function is used in Thieler et al. (2013).
