The day after the heliacal rising of θ Arae coincided with the December solstice. At the other end of the year, in June 18, was the 'whip' of the Charioteer, formed by Praja-pāti (δ), Menkalinan, and Mahashim (θ):

It seems likely the creator of the C text has placed the heliacal rising of these important stars at 3-14 (π) to indicate the position halfway through the year.

In my arrangement of opposite night stars in parallel with the heliacal stars my method has basically been to use the key numbers 181 and 184. From a heliacal star to its nakshatra star there should be around 181 days. E.g. Praja-pāti (89.3) + 181 = ca 270 and Praja-pāti (89.3) + 184 = ca 273.

Although my table over important star pairs - first the heliacal star and then the other ca 181 days later - in principle is beginning at 0h, I have recently chosen to add 184 instead of 181 to find the star close to the Full Moon in the night, e.g. with Thuban (212.8) - Alrisha (29.2) = ca 184:

Alrisha (29.2) + 365¼ - 212.8 = 181.65 = ca 181. By counting past the end of the Gregorian year my rule for finding the nakshatra star by adding 181 will lead to Thuban (α Draconis) at the other side of the sky compared to Alrisha. The glyph number 395 (> 365) indicates we maybe should add 184 instead of 181.

Earlier I have used another method, viz. to add 365¼ / 2. This method would have resulted in a night-side star for Praja-pāti at position 89.3 + 182.625 = 271.925. Although θ Arae would still be close to the Full Moon in the night before the December solstice its position in my interpretation of the C text would be pushed ahead to a mirror date 2 days after June 19, i.e. it would be in the night sky of the June solstice.

My earlier method thus seems to be more in harmony with the time of the December solstice and therefore I possibly ought to rearrange the beginning of side b into:
