SEM DAILY AVERAGE FULL SOLAR DISK FLUX at 1 AU ARE ARCHIVED TO THE ZIP FILE: zip_daily.zip
When unzipped, each year file, e.g. 17_v3.day for 2017 contains daily averaged SEM data
The data are organized in 15 columns with explanation in the file headers

Column 0-	Julian date (mid point of sample)
Column 1-	Year (UT)
Column 2-	Day of Year (UT)
Column 3-	CH1 (1)
Column 4-	stdev CH1
Column 5-	CH2 (1)
Column 6-	stdev CH2
Column 7-	CH3 (1)
Column 8-	stdev CH3
Column 9-	X (2)
Column 10-	Y (2)
Column 11-	Z (2)
Column 12-	R (3)
Column 13-	R (AU)
Column 14-	First Order Flux at 1AU (4)
Column 15-	Central Order Flux at 1AU (5)-----------------------------------------------
(0) Blank or Zero values = no data
(1) Daily average (raw) count rate at SOHO
(2) SOHO Heliocentric location, X, Y, & Z (km)
