New Features in PSRCHIVE 13.4

Version 13.4 is primarily a bug fix distribution. See the Bugs Tracker for more information.

New Features in PSRCHIVE 13.3

Rotating Vector Model: psrmodel now provides more control over model parameters, including the ranges of alpha and zeta/beta over which to search for the best fit.

Arrival Time Estimation: pat now provides access to any parameter understood by psrstat, which can be output with the arrival time when tempo2 format and the -C <keyword> option is used.

New Features in PSRCHIVE 13.2

There are no new features or bug fixes in version 13.2. This release was made only to support the most recent parallel developments in the DSPSR project.

New Features in PSRCHIVE 13.1

Survey candidate refinement: A number of improvements have been made to pdmp, related to computational efficiency, ease of use, and correctness of results. Big thanks to Andrew Lyne for important suggestions and repeated testing.

New Features in PSRCHIVE 13.0

Data visualization: psrplot can now flip the frequency axis on phase-vs-frequency plots (e.g. if the data are lower-sideband and frequency increasing on the y-axis is preferred.

Timing: pat supports new arrival time estimation algorithms, including a multiple varying component model (the same used by paas) that allows the relative heights of components to vary.

Polarimetric calibration: pcm has been updated to do its best at measurement equation modeling without any calibrators. This feature should be used with caution, as the initial guess can be quite far from the best fit without this information.

General data reduction: When combining the observations from multiple sub-bands using psradd -R, psradd can now patch up any missing data with a sub-integration that has zero weight.
