Voyager 1: Proton Differential Fluxes, 1-hour averages
=======================================================================
Each file in this directory contains one year's worth of data from the
LECP instrument on the Voyager 1 spacecraft. Each record in a file
contains 1-hour averages of fluxes and flux uncertainties of protons in
the energy channels shown in the table below. Each file contains a
2-line header that identifies the spacecraft, data type and time
resolution, and labels each column of data. Statistical uncertainties
represent one standard deviation.

Differential (in energy) flux units are: protons/(cm^2 sec ster MeV).

A record contents is as follows:
-----------------------------------------------------------------------
column	label		description
-----------------------------------------------------------------------
1	year		4-digit year
2	doy		day of year (1-365 or 366)
3	hr		hour of day (0-23)
4	dec_year	decimal year (double precision)
			= year + (doy - 1 + hr/24)/dpy (dpy=365 or 366)
5	dec_doy		decimal day of year = doy + hr/24
6	ch1_flux	flux, protons 0.57-1.78 MeV
7	ch1_fluxu	stat. unc. of above flux
8	ch16_flux	flux, protons 3.40-17.6 MeV
9	ch16_fluxu	stat. unc. of above flux
10	ch23_flux	flux, protons 22.0-31.0 MeV
11	ch23_fluxu	stat. unc. of above flux
