### Python Modeling — celerite 0.4.0 documentation

2021-1-29 · A Simple Mean Model¶. The model that we ll fit in this demo is a single Gaussian feature with three parameters amplitude (alpha) location (ell) and width (sigma 2).I ve chosen this model because is is the simplest non-linear model that I could think of and it is qualitatively similar to a few problems in astronomy (fitting spectral features measuring transit times etc.).

### Kronecker s delta João H de A Franco

Posts about Kronecker s delta written by JHAF. Maximum length sequences (or m-sequences) are bit sequences generated using maximal LFSRs (Linear Feedback Shift Registers) and are so called because they are periodic and reproduce every binary sequence that can be represented by the shift registers (i.e. for length-m registers they produce a sequence of length ).
