示例1: translate_and_query
def translate_and_query(self, hek_results, limit=None,

"""
Translates HEK results, makes a VSO query, then returns the results.
Takes the results from a HEK query, translates them, then makes a VSO
query, returning the results in a list organized by their
corresponding HEK query.
Parameters
----------
hek_results: sunpy.net.hek.hek.Response or list of sunpy.-.-.-.Response
The results from a HEK query in the form of a list.
limit: int
An approximate limit to the desired number of VSO results.
full_query: Boolean
A simple flag that determines if the method is being
called from the full_query() method.
use_progress_bar: Boolean
A flag to turn off the progress bar, defaults to "on"
Examples
--------

示例3: _gaussian_fits

"""
Returns an array of fit objects from which parameters can be extracted
corresponding to the line guesses provided.
Parameters
----------
line_guess and extra_lines: 3-tuples of floats
There must be at least one guess, in the format (intensity,
position, stddev). The closer these guesses are to the true values
the better the fit will be. If left to None, each of the individual
spectra will come up with their own guesses. This only works for
cubes with clean, single-line spectra.
recalc=False: boolean
If True, the gaussian fits will be recalculated, even if there's an
existing fit for the given wavelengths already in the memo. This
keyword should be set to True if changing the amplitude or width of
the fit.
**kwargs: dict
Extra keyword arguments are ultimately passed on to the astropy
fitter.
