Notes. Units of right ascension (RA) are hours, minutes, seconds and units in declination (Dec) are degrees, arcminutes and arcseconds (J2000.0). Sizes are given as the major axis diameter times the minor axis diameter of an elliptical object (only one value if circular). FUV fields are expressed in units of the Habing field which represents the estimated average FUV flux in the local interstellar medium (Habing 1968).
