छित्त्वाऽर्धेन:
It has 'ध' with 'े' and repha 'र्'.
Now compare that with line 10:
In line 10, the letter has 'थ' or 'ध'?
Wait, look at footnote 1: "१. वृत्तार्धं—क०;" -> वृत्तार्धं has 'र्ध'.
In line 10, let's look at the letter: it has an open top? 'थ' has a closed loop and breaks the headline (shirorekha).
In line 10, does the shirorekha break over that letter?
Yes, it does! Wait, both 'थ' and 'ध' break the shirorekha in Devanagari!
Wait, but is it 'र्धे' or 'र्थे'?
Let's check if it's 'चात्यर्धे' or 'चात्यर्थे':
In many Sanskrit texts, we see "चात्यर्धे" or "चात्यर्थे".
Wait, look at the letter itself: it's round at the bottom, like 'ध'. 'थ' curves down to the line then goes right to the vertical stem. 'ध' has two rounded bellies!
Look at line 10: it has two rounded bellies! That is a 'ध'!
And does it have a repha? Yes, there's a curve attached to the e-matra: 'र्धे'.
So it is `चात्यर्धे
