[..] optional| Parameter | Default value | Discussion |
|---|---|---|
| net[work] | - | Seismic network name. |
| sta[tion] | - | Station name. |
| loc[ation] | - | Location code. Use loc=-- for empty location codes. |
| cha[nnel] | - | Channel Code. |
| time | - | Evaluate the response at the given time. If not specified, the current time is used. |
| minfreq | 0.00001 | The minimum frequency (Hz) at which response will be evaluated. |
| maxfreq | - | The maximum frequency (Hz) at which response will be evaluated. Defaults to the channel sample rate or the frequency of sensitivity, whichever is larger. |
| nfreq | 200 | Number frequencies at which response will be evaluated. Must be a positive integer no greater than 10000. |
| units | def | Output unit. Must be: def (unit in response metadata), dis (displacement), vel (velocity), acc (acceleration). |
| spacing | log | Scale frequency. Must be: lin(ear) or log(arithmic). |
| width | 800 | The width of the generated plot. Defaults to 800. |
| height | 600 | The height of the generated plot. Defaults to 600. |
| annotate | true | Displays the sensitivity, the frequency and sensitivity frequency. |
| degrees | false | Displays the phase in degrees or in radians. |
| format | plot | Output format. Must be: fap (three column ASCII: frequency, amplitude, phase), cs (three column ASCII: frequency, real, imaginary), plot (amplitude and phase plot), plot-amp (amplitude only plot), plot-phase (phase only plot). |
| nodata | 404 | Specify which HTTP status code is returned when no data is found (204 or 404) |
