CGFILL fills specified gaps in the data given an inital guess for the spectrum. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: CGFILL fills specified gaps in the data given an inital guess for the spectrum using the constrained gaussian method. CALL: out = obj.cgfill(pl) out = cgfill(objs, pl) INPUTS: pl - a parameter list obj(s) - input ao object(s) OUTPUTS: out - filled data series. Created 2013-02-20, M Hewitson - adapted from code writen by Curt Cutler and Ira Thorpe. Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

| Key | Default Value | Options | Description |
| NFFT | -1 | none | The number of samples in each fft [default: length of input data]. A string value containing the variable 'fs' can also be used, e.g., plist('Nfft', '2*fs') |
| WIN | 'BH92' |
|
The window to be applied to the data to remove the discontinuities at edges of segments. [default: taken from user prefs] Only the design parameters of the window object are used. Enter a string value containing the window name e.g. plist('Win', 'Kaiser', 'psll', 200) plist('Win', 'BH92') |
| PSLL | 200 | none | The peak sidelobe level for Kaiser windows. Note: it is ignored for all other windows |
| OLAP | -1 | none | The segment percent overlap [-1 == take from window function] |
| ORDER, N | 0 |
|
The order of segment detrending:
|
| NAVS | -1 | none | Force number of averages. If set, and if Nfft was set to 0 or -1, the number of points for each window will be calculated to match the request. |
| TIMES, SPLIT | [] | none | The time range to analyze. If not empty, sets the time interval to operate on. As in ao/split, the interval can be specified by:
|
| SCALE | 'PSD' |
|
The scaling of output. Choose from:
|
| ORDERS | 0 | none | The powers of the dependent variable to fit to the data. |
| P0 | 1 | none | An initial guess for the power-law coefficients. |
| INDICES | [] | none | List of start/stop index pairs for data to be subsituted (Nx2). Can either be an array of doubles or a cdata ao |
| SAMPLES | [] | none | The number of samples to truncate the correlation vector to. If empty, the full inverse correlation vector will be returned. |
| F TRIM | [0 Inf] | none | The range of frequencies (lower and upper) of the spectrum when fitting the spectral model. |
| BIN SPECTRUM | 1 |
|
Choose whether or not to smooth the spectral data before fitting using ao/bin_data. |
| MODE | 'iterate' | none | The method for deciding when to end the filling procedure:
|
| NITER | 1 | none | The number of iterations to perform for the 'iterate' mode. |
