Presenting / printing Right Ascension and Declination values
There are no standards for representing right ascension and declination apart from the abbreviations RA and Dec, and the symbols $\alpha$ and $\delta$.

The use of decimal degrees, dms, °'", hours and decimals, hms etc. depend on the [author's] style and intent. For example, determining transit times from local sidereal time and right ascension is easier when RA is expressed in hours, whereas doing calculations of angular separation is easier to calculate in software when decimal degrees are used.
