Commentary

The words 1. कूल 2. सूद 3. स्थल and 4. कर्ष have acute accent (उदात्त) on their first syllable when at the end of a तत्-पुरुष समास denoting a Name.
Thus दाक्षिकू꣡लम्, आहकिकू꣡लम्, देवसू꣡दम्, भाजीसू꣡दम्, दाण्डायनस्थ꣡ली, माहकिस्थ꣡ली, दाक्षिक꣡र्षः ॥ All these are names of villages. The feminine of स्थल is taken here, formed by ङीष् 4.1.42. When not a name we have परमकूलम् ॥
