example usage:
1. create a dedispersed time series with presto,
e.g. 'prepdata myobservation.fits -dm 500 -nobary -o topocentric_timeseries'
2. convert dedispersed time series .dat and .inf files to a einstein@home .binary,
e.g. 'presto2einstein ./topocentric_timeseries'
3. run the einstein@home client in standalone mode against the new topocentric_timeseries.binary
file -
- download the einstein@home binary radio pulsar (BRP) stand alone client from
http://einstein.phys.uwm.edu/download/
- The latest non-gpu linux client at the time of this writing was at:
http://einstein.phys.uwm.edu/download/einsteinbinary_BRP4_1.22_i686-pc-linux-gnu__BRP4SSE
- It's a little tricky to get the BOINC build to produce command line help, but it appears to
accept all the arguments none-the-less. Here is the command line help, taken from the
demod_binary.c source:
Usage: <executable> [options], options are:"
-h, --help boolean Print this message
-i, --input_file string The name of the input file.
-o, --output_file string The name of the candidate output file.
-t, --template_bank string The name of the random template bank.
-c, --checkpoint_file string The name of the checkpoint file.
-l, --zaplist_file string The name of the zaplist file.
-f, --f0 float The maximum signal frequency (in Hz)
-A, --false_alarm float False alarm probability.
-P, --padding float The frequency over-resolution factor.
-W, --whitening boolean Switch for power spectrum whitening and line zapping.
-B, --box int Window width for the running median in frequeny bins.
-D, --device integer The GPU device ID to be used.
-U, --username string Name of the BOINC user running the current instance.
-H, --host-cpid int Identifier of the BOINC host running the current instance.
-z, --debug boolean Run program in debug mode.
An example usage, taken from the source's Makefile test is:
einsteinBRP -t ./stochastic_full.bank -A 0.04 -P 3.0 -i ./topocentric_timeseries.binary \
-l ./zap.txt -c status -o results -z -W
Results are output to 'results' in the cwd.
The three columns in the orbit template bank are:
P: orbital period of the binary in seconds
tau: lighttravel time for projected binary semi-major axis
Psi0: initial orbital phase
The columns in the output file are (I think):
f: frequency in Hz
P_b: period of the binary in seconds
tau: light travel time for the projected semi-major axis
Psi: initial orbital phase
Power: signal strength in stddev
fA: false alarm probability in some unkown units
n_harm: number of harmonics summed
