The glyph distance from a place close to the Full Moon to its return from invisibility close to the Sun was not 366 / 2 = 183 days but 183 + 16 = 199 days.

However, the number of days from the Front of the Head of Ku (Sheratan) to Menkar was probably 365 + 123 (May 4, 5-4) - 290 (October 17) = 198 due to the fact that 365 < 365¼ in combination with my suggestion of how to understand Cb1-12 (at heliacal Toliman).

Moreover, the 4 years needed to increase the remainder ¼ to 1 day must have been documented all through history, and a natural place for the sudden jump (leap) was Toliman:

"It bore an important part, too, in southern China as the determinant of the stellar division Nan Mun, the South Gate [cfr Yang Mun, α Lupi].

α lies in the Milky Way, 60º south [60° 38′] of the celestial equator, culminating with Arcturus [in June 14 and 6 days after Arcturus], but is invisible from north of the 29th parallel.

It is of the greatest interest to astronomers, being, so far as is now known, the nearest to our system of all the stars, although more than 275,000 times the distance of the earth to the sun, - 92,892,000 miles, - and 100 millions of times the distance from the earth to the moon, - 238,840 miles.

Its parallax, first taken at the Cape of Good Hope by Henderson in 1839, and later by Gill and Elkin, and now fixed at 0".75, shows a distance equal to that travelled by light in 4⅓ years. We can better realize the immensity of this distance from Professor Young's statement that if the line from the earth to the sun's centre be represented as 215 feet long, a line to this star would be 8000 miles; and from Sir John Herschel's illustration:

to drop a pea at the end of every mile of a voyage on a limitless ocean to the nearest fixed star, would require a fleet of 10,000 ships of 600 tons burthen, each starting with a full cargo of peas."

Finally, it should be noticed that Crux lies inside the Centaur with the Southern Fly (Musca) further down:
