Origin of time for the periodicity test.

If START or STOP is chosen, the start or stop time is taken from the input event file(s) and used as the time origin.

If MIDDLE is chosen, the mid-time between START and STOP is used.

If USER is chosen, user will supply explicitly using usertime, userformat and usersys parameters.

String describing the representation used for the usertime.

If FILE is chosen, the time format specified in the input event file header will be used. Used only if timeorigin parameter is USER.

String describing the time system used for the usertime.

If FILE is chosen, the time system specified in the input event file header (TIMESYS keyword) will be used. Used only if timeorigin parameter is USER.

Method to specify how the ephemerides will be supplied.

If ephstyle is DB, a pulsar database file in Fermi (formerly GLAST) D4 FITS format will be used.

If ephstyle is FREQ (PER), the user will supply values for the frequency (period) and its derivatives at the time given by the epoch parameter.

Set of arrival time corrections to apply.

If tcorrect is NONE, no corrections will be applied. If tcorrect is BARY, only the barycentric correction will be applied. If tcorrect is BIN, an appropriate orbital ephemeris is searched for in the pulsar database, and if found, binary demodulation will be applied after the barycentric correction, and if not, an error will be generated. If tcorrect is PDOT, an appropriate spin ephemeris is searched for in the pulsar database, and if found, pdot cancellation will be applied after the barycentric correction, and if not, an error will be generated. If tcorrect is ALL, both actions for the BIN option and the PDOT option will be taken. If tcorrect is AUTO, the barycentric correction will be applied, and the binary demodulation will be applied only when an orbital ephemeris is available in the pulsar database, then the pdot cancellation will be applied only when a spin ephemeris is available in the pulsar database.

String that controls whether to use the name of the solar system ephemeris given by the solareph parameter to check the input event data file and to select ephemerides in the pulsar database.

If matchsolareph is EVENT, all the input event files are required to use the same solar system ephemeris for the barycentric correction as the one given by the solareph parameter, and an error will be generated if otherwise. Such an error may occur when an input event data file has already been applied the barycentric correction with a different solar system ephemeris. If matchsolareph is PSRDB, the string given by the solareph parameter is used to select the ephemerides. If matchsolareph is ALL, both actions for the EVENT option and the PSRDB option will be taken. If matchsolareph is NONE, no selection will be performed.

Angular tolerance in degrees in comparison of two source positions, one for which the barycentric correction is performed, and another given by RA_NOM and DEC_NOM header keyword of an event file to which the barycentric correction has already been applied.

This parameter only has effect if the barycentric correction has been applied to an input event data file. If the two source positions are separate from each other by this amount or less, they will be considered to be the same position. Otherwise an error will be generated. The sign of the parameter value is ignored. For example, setting angtol=-1.0 results in giving angular tolerance of 1 degree.

Activate debugging mode. (default: no)

When debug is "no", all exceptions that are not caught and handled by individual tool-specific code are caught by a top-level exception handler that displays information about the exception and then exits.

When debug is "yes", such exceptions are not caught by the top level code. Instead the tool produces a segmentation violation, which is more useful for debugging. When debugging mode is enabled, the tool produces more verbose output describing any errors or exceptions that are encountered.
