|
| VOLT_WAVEFORM | STRING | NULL | <filename>=<x>+<y> form specification of input file giving voltage waveform factor vs time |
|
| PHASE_WAVEFORM | STRING | NULL | <filename>=<x>+<y> form specification of input file giving phase offset vs time (requires FREQ_WAVEFORM) |
|
| FREQ_WAVEFORM | STRING | NULL | <filename>=<x>+<y> form specification of input file giving frequencyfactor vs time (requires PHASE_WAVEFORM) |
|
| FIDUCIAL | STRING | NULL | mode for determining fiducial arrival time (light, tmean, first, pmaximum) |

Explanation of <filename>=<x>+<y> format: Several elements in elegant make use of data from external files to provide input waveforms. The external files are SDDS files, which may have many columns. In order to provide a convenient way to specify both the filename and the columns to use, we frequently employ <filename>=<x>+<y> format for the parameter value. For example, if the parameter value is waveform.sdds=t+A, then it means that columns t and A will be taken from file waveform.sdds. The first column is always the independent variable (e.g., time, position, or frequency), while the second column is the dependent quantity.
