Precise instructions for downloading datasets

[diethardsteiner]

As a reader of your book I'd like to be able to download the various sample datasets that you use for examples without spending a long time figuring out how you arrived at the selection of the data points. Currently I am reading chapter 4 and trying to download the Voyager 1 dataset, however, there are millions of options. I'd appreciate if you could provide some instructions on how to get the correct datasets for your examples/code.

Ok, for anyone else trying to find the correct dataset for chapter 4, here are the instructions:

How to obtain the source data - Chapter 4

On the first page just tick Voyager and click the submit button. On the next page untick all options apart from:

VOYAGER1_COHO1HR_MERGED_MAG_PLASMA: Merged hourly magnetic field, plasma, proton fluxes, and ephemeris data - Norman F. Ness (Bartol Research Institute)
      [Available Time Range: 1977/09/07 00:00:00 - 2015/12/31 22:00:00]

Click the Submit button.

On the next page select List Data (ASCII) and tick Output listing times as year and seconds of year.

Scroll down to the VOYAGER1_COHO1HR_MERGED_MAG_PLASMA section and tick all fields.

Click the Submit button.

Click on the Listing link.

Note: The field separator is different (it seems) than the one used in the code.
