LPSD computes the log-scale PSD of the time-series AOs in a ltpda_container object. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: LPSD computes the log-scale PSD of the time-series AOs in a ltpda_container object. CALL: out = lpsd(in, pl); Note: this is just a wrapper of ao/lpsd. Each AO in the ltpda_container is passed to ao/lpsd with the input plist. INPUTS: in - input ltpda_container objects pl - parameter list OUTPUTS: out - output ltpda_container objects Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Key | Default Value | Options | Description |
KDES | 100 | none | The desired number of averages. |
JDES | 1000 | none | The desired number of spectral frequencies to compute. |
LMIN | 0 | none | The minimum segment length. |
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 | 0 |
|
The order of segment detrending:
|
TIMES | [] | 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:
|
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:
