There is no ZD or PK catalog listed in the standard astronomical
reference for such things (the SIMBAD database); I'm sure you know that
the familiar names would have been invented even if the stars had not.
My guess is that the author invented these catalogs out of whole
cloth; they probably refer to existing stars under other names. Those
numbers didn't yield anything nearby in any of the commonly used
catalogs (HR, HD, or SAO).

That's an M4. And assuming that the units you have parallax in are
milliarcseconds, that's the right distance.
