computebisector_biserr

raccoon.ccf.computebisector_biserr(x, y, xerr, n=100, bybotmin_percent=10.0, bybotmax_percent=40.0, bytopmin_percent=60.0, bytopmax_percent=90.0, xrealsampling=None, verb=True, returnall=False)

Compute bisector, bisector inverse slope (BIS) and their errors.

Same code as in functions computebisector to compute the bisector and in computebisector_bis to compute the BIS. Copied here because intermediate products needed to compute the BIS error.

If do not need the BIS error, use the other functions - computebisector - computebisector_bis

Parameters:

x, y

xerr

nint (default 100)

bybotmin_percent, bybotmax_percentfloat

Bisector bottom region limits in percentage.

bytopmin_percent, bytopmax_percentfloat

Bisector top region limits in percentage.

xrealsamplingfloat (default None)

Sampling of the real data. Usually the input data provided (x and y) is oversampled in order to correctly compute the bisector. So need to provide what would be the real sampling in order to compute the BIS error properly.

bybotmin_percent …

verb

returnallbool (default False)

Output a lot intermediate of products.

Returns:
