What’s new¶

New features¶

• The heliopy.data.ace module now contains all the magnetic field and particle data produces produced by ACE. #577, #578
• STEREO-A spice kernels have been added. #585

Bug fixes¶

• The accidentally removed Ulysses spice kernel has returned. #582
• heliopy.data.helper.cdfpeek has been updated to work with cdflib, and now prints all CDF file information.

New features¶

• HelioPy has been integrated with SunPy TimeSeries and AstroPy Units. All of the HelioPy modules now return physical units with data.
• Added a new data.util.cdf_units() function that can extract the UNIT attribute from CDF files.
• Low resolution OMNI data import has been added in data.omni.low() function.
• Magnetic Field data from DSCOVR Spacecraft can now be imported using the data.dscovr.mag_h0() function.

Backwards incompatible changes¶

• Methods in heliopy.data no longer returns a Pandas DataFrame, but now return a SunPy timeseries object. To get the underlying data, you can still do:

  dataframe = timeseries.data
  

  For an example of how to use the new object, see TimeSeries Plotting Example.

• Data import has had a major overhaul, so that every column in CDF files now gets automatically imported and retains its name without being changed by HelioPy. This means column names in several data products are now different, to reflect their original name in the CDF files instead of a custom name that was previously assigned by HelioPy.

• data.helios.merged(), data.helios.mag_4hz(), data.helios.corefit() and data.helios.mag_ness() no longer take a verbose keyword argument. #467

Fixed bugs¶

• data.imp.merged() no longer imports redundant columns.

New features¶

• Lots of small documentation updates.
• .data.helios.distparams now has an extra 'data_rate' column, which determines whether a given distribution function was transmitted in high or low data mode. #529

New features¶

• The new HelioPy logo has been added to the documentation. #448, #447

Fixed bugs¶

• The new data version number of data.mms.fpi_dis_moms() has been updated.

New features¶

• HelioPy can now be installed using conda.

Backwards incompatible changes¶

• The list of kernels available for automatic download in data.spice has been updated, and some names changed. #408

Fixed bugs¶

• spice.Trajectory.generate_positions() can now generate positions at a resolution of one second instead of one day. #405
• A duplicate “z gsm” column header in the data returned by data.imp.mag15s() has been corrected. #396

New features¶

• heliopy.data.sunspot() added an additional functionality to import sunspot data in three different timeframes - daily, monthly and yearly.
• The inventory of spice kernels in heliopy.data.spice now includes “Helios 1 Reconstructed”, “Helios 1 Predicted”, “Juno Reconstructed”, “Juno Predicted” and “Helios 2” kernels.
• heliopy.spice.furnish() now accepts a list of filenames as well as individual filenames.
• A lot of new functions for downloading ACE data have been added to heliopy.data.ace.

Backwards incompatible changes¶

• heliopy.data.spice.get_kernel() now returns a list of filenames instead of a single filename string.
• Most of the functions that were in heliopy.data.helper have been moved to heliopy.data.util. The ones the remain in heliopy.data.helper are useful for users, and the ones in heliopy.data.util are used internally as utility functions for data import.

Removed features¶

• heliopy.data.helios.trajectory() has been removed. To get Helios trajectory data use the heliopy.spice and heliopy.data.spice modules.

New features¶

• swics_abundances() and swics_heavy_ions() methods added for loading SWICS data from the Ulysses mission.
• cdfpeek() method added for peeking inside CDF files.

Backwards incompatible changes¶

• heliopy.spice.Trajectory.generate_positions() now takes a list of dates/times at which to generate orbital positions, instead of a start time, stop time, and number of steps. The old behaviour can be recovered by manually generating an evenly spaced list of times.

New features¶

HelioPy now contiains code for working with SPICE kernels. See the following modules for more information:

• heliopy.data.spice module for downloading spice kernels
• heliopy.spice module for automatically processing spice kernels

Removed features¶

• The heliopy.plasma module has been removed (see http://www.plasmapy.org/ for the recommended alternative)
• heliopy.plot code removed

New features¶

• Convert examples gallery to automatically generate plots
• Added HelioPy.data.helper.listdata() method for easily viewing the amount of data HelioPy is storing locally.
• Added heliopy.data.wind.threedp_sfpd() method for importing WIND 3DP sfpd data.

Fixed bugs¶

• Correctly report download percentage when downloading files.
• Fix issue where heliopy.data.helios.corefit() made duplicate .hdf files on days where no data is available.
