set_getsnr_function(connection, statistic)

source code

Set the get_snr SQL function. Available options are: -- "rawsnr", "newsnr", "effsnr", "snroverchi"

all_sngl_snr_hist(connection, mchirp, eta, all_ifos, min_snr=5.5, sngls_width=0.01, snr_stat=None)

source code

Creates a pair of dictionaries containing single-ifo snr histograms and their associated snr bins. The keys are the instruments filtered in the analysis.

all_possible_coincs(sngl_ifo_hist, sngl_ifo_midbins, combined_bins, ifos)

source code

Creates a histogram of all possible coincident events and returns a list of counts in each of the snr bins. This is made using the single-ifo snr histograms.
