. Note: using scientific notation assumes that the returned value will be enclosed in LaTeX math mode.include_error ({True, bool}) – Include the error in the return string; the output will be formated val pm err, where err is the error rounded to the same power of 10 as val. Otherwise, just the formatted value will be returned. If plus_error is provided then the return text will be formatted as
val^{+plus_error}_{-error}
.use_relative_error ({False, bool}) – If include_error, the error will be formatted as a percentage of the the value.
ndecs ({None, int}) – Number of values after the decimal point. If not provided, it will default to the number of values in the error.
- Returns:
The value (and error, if include_error is True) formatted as a string.
- Return type:
string
Examples
Given a value and its uncertainty:
>>> val, err (3.9278372067613837e-22, 2.2351435286500487e-23)
Format with error quoted:
>>> format_value(val, err) '3.93 \pm 0.22\times 10^{-22}'
Quote error as a relative error:
>>> format_value(val, err, use_relative_error=True) '3.93 \times 10^{-22} \pm5.6\%'
Format without the error and without scientific notation:
>>> format_value(val, err, use_scientific_notation=float('inf'), include_error=False) '0.000000000000000000000393'
Given an plus error:
>>> err_plus 8.2700310560051804e-24
Format with both bounds quoted:
>>> format_value(val, err, plus_error=err_plus) '3.928^{+0.083}_{-0.224}\times 10^{-22}'
Format with both bounds quoted as a relative error:
>>> format_value(val, err, plus_error=err_plus, use_relative_error=True) '3.928\times 10^{-22}\,^{+2.1\%}_{-5.7\%}'
pycbc.results.table_utils module

columns (list of numpy arrays)
names (list of strings) – The list of columns names
page_size ({int, None}, optional) – The number of items to show on each page of the table
format_strings ({lists of strings, None}, optional) – The ICU format string for this column, None for no formatting. All
provided. (columns must have a format string if)
