get_delta_t_rss(pt,
coinc,
reference_frequency=None)
returns the rss timing error for a particular location in the sky
(longitude,latitude) |
source code
|
|
|
|
get_signal_duration(ifo,
coinc,
frequency)
determine the amount by which the coalescence time must be translated
to get the reference time |
source code
|
|
|
|
get_delta_D_rss(pt,
coinc)
compute the rms difference in the ratio of the difference of the
squares of Deff to the sum of the squares of Deff between the
measured values and a "marginalized" effective distance
this is just the squared Deff integrated over inclination and
polarization which is proportional to (F+^2 + Fx^2)^(-1) |

gridsky(resolution,
shifted=False)
grid the sky up into roughly square regions resolution is the length
of a side the points get placed at the center of the squares and to
first order each square has an area of resolution^2 if shifted is
true, the grids are reported with latitudes in (0,pi). |
source code

|
|
|
map_grids(coarsegrid,
finegrid,
coarseres=4.0)
takes the two grids (lists of lat/lon tuples) and returns a
dictionary where the points in the coarse grid are the keys and lists
of tuples of points in the fine grid are the values |

gaussian_kde(data,
x,
w)
kernel density estimate of the pdf represented by data at point x
with bandwidth w |
source code
|
|
|
|
_gauss_kern(x,
xn,
w)
gaussian kernel for kernel density estimator |
source code

|
|
percentile(p,
dat)
compute p%-tile of data in dat |
source code
|
|
|
|
iqr(data)
computes the interquartile range of data useful for determing widths
of bins in histograms or bandwidths in kdes |
source code
|
|
|
|
lonlat2polaz(lon,
lat)
Convert (longitude, latitude) in radians to (polar, azimuthal) angles
in radians. |
source code

sbin(bins,
pt,
res=0.4)
bin points on the sky returns the index of the point in bin that is
closest to pt |

populate_SkyLocInjTable(skylocinjtable,
coinc,
rank,
area,
dtrss_inj,
dDrss_inj,
grid_fname,
gal_grid)
record injection data in a skylocinjtable |
source code

populate_GalaxyTable(galaxytable,
coinc,
galaxy)
record galaxy data in a galaxytable |
source code
