The TimeSeriesMetaData class

This provides an overview of the basic functionality of the TimeSeriesMetaData class.

import astropy.units as u

import sunpy.data.sample
import sunpy.timeseries
from sunpy.net import Fido, attrs as a
from sunpy.time import TimeRange, parse_time

Search for Data

goes_res = Fido.search(a.Time("2010-11-02", "2010-11-07"), a.Instrument('XRS'))
norh_res = Fido.search(a.Time("2010-11-02", "2010-11-07"), a.Instrument('norh'),
                       a.Wavelength(17 * u.GHz))

Out:

/home/docs/checkouts/readthedocs.org/user_builds/sunpy/conda/stable/lib/python3.7/site-packages/astropy/units/quantity.py:1070: AstropyDeprecationWarning: The truth value of a Quantity is ambiguous. In the future this will raise a ValueError.
  AstropyDeprecationWarning)

Download the data and load it

goes_files = Fido.fetch(goes_res)
norh_files = Fido.fetch(norh_res)

goes_ts = sunpy.timeseries.TimeSeries(goes_files, source='XRS', concatenate=True)
norh_ts = sunpy.timeseries.TimeSeries(norh_files, source='NoRH', concatenate=True)

The TimeSeriesMetaData class stores all the individual file metadata MetaDict objects as 3-tuple entries in it’s internal list with the TimeRange, list of column names and metadictionary. This list is stored in order of ascending TR.start. Access of the the list is done using the metadata property:

large_ts.meta.metadata

The TimeSeriesMetaData class has a number of other properties, including the timerange property that returns a TimeRange for the entire metadata:

large_ts.meta.time_range
# Further properties can be used to get lists of details, such as:
# lists of the values:
large_ts.meta.timeranges  # List of the time ranges
large_ts.meta.columns  # List of the column names
large_ts.meta.metas  # List of the meta dictionaries

When you truncate the TimeSeries, the metadata is truncated too:

large_trunc_ts = large_ts.truncate(TimeRange('2010-11-03 13:59:57.468999',
                                             '2010-11-05 13:59:56.091999'))
print(large_trunc_ts.meta.to_string(2))

Finding metadata can be achieved using the find method and applying filters for time and/or colname. This returns another TimeSeriesMetaData object:

large_trunc_ts.meta.find(time=parse_time('2010-11-04 09:01:16'))
large_trunc_ts.meta.find(time='2010-11-04 09:01:16', colname='xrsb')

# You can get the time of a row a from the TimeSeries object's index:
large_trunc_ts.meta.find(time=large_trunc_ts.index[10])

# Note: with no filters you get a duplicate of the original TimeSeriesMetaData
# object.

There is also a get method:

large_trunc_ts.meta.get('telescop')

# Again, filters can be used:
large_trunc_ts.meta.get('telescop', time='2010-11-04 09:01:16', colname='xrsb')

# And if we just want the values, the values method returns just a list:
large_trunc_ts.meta.get('telescop').values()

Out:

['GOES 15', 'RADIOHELIOGRAPH']

You can update values similar to dictionaries, though all of the contained MetaDict objects will be updated that match your filter criteria:

large_trunc_ts.meta.update({'new_key_1': 'added to all.'})
large_trunc_ts.meta.update({'new_key_2': 'added to some.'}, colname='xrsa')
print(large_trunc_ts.meta.to_string(2))

# but you can't overwrite previous entries without setting the overwrite kwarg,
# this is to protect the integrity of the metadata:

large_trunc_ts.meta.update({'new_key_1': 'changed'}, overwrite=True)
print(large_trunc_ts.meta.to_string(2))
