While the first line on side a has 26 glyphs the first line on side b has 24 glyphs. This could be Signs of 'south of the equator' respectively 'north of the equator':

Antares was rising with the Sun at declination 26º S and the Pleiades were setting with the Sun at declination 24º N. The power of numbers could have connected 24 with the beginning of 24h and 26 with the beginning of 26 decades of days. And 24 + 26 = 50 (= 5 = 500) - adding zeroes would not have changed the core.

When Tau-ono were setting with the Sun they surely also must have risen with the Sun and we know this happened 56 days after March 21. 80 + 56 = 136 (May 16) = Alrescha 15 (365)

Possibly there were 5 + 5 = 10 women and 1 male, Atlas, who culminated in December 30-31. However, of these stars only 3 + 5 = 8 were 'women stars' in the Pleiades. Atiks (the name in my astronomy book) is οmikron at the left heel of Perseus and Rana (the Frog) is δ Eridani.

"Atiq (also transliterated as Ateek, Ateeq, Attiq, Atik, or Attique ...‎) is a male Arabic given name, the name is used in the Quran ... 'Old or Ancient' ... (Wikipedia)
