ReadonlyepochWhen value holds, read as time is: { jd, scale: "tt" } is
SE_SIDM_USER's TT epoch, and { jd, scale: "ut1" } its UT epoch
(SE_SIDBIT_USER_UT), whose TT comes from the time basis.
Optional ReadonlymodelWithout rate: the model value was computed with, default "engine". An older model's zodiac is held where that model puts it at J2000.0.
Optional ReadonlynameA lowercase identifier of at most 64 characters that is not a built-in name; default "user".
Optional ReadonlyrateArcseconds per Julian year, from −3600 to 3600: an ayanamsa that grows by this rate, with no precession model.
ReadonlyvalueThe mean ayanamsa at epoch, degrees, from −360 to 360.
A caller's ayanamsa, the counterpart of Swiss Ephemeris's SE_SIDM_USER: the mean ayanamsa
valueatepoch, carried from there by precession inmodel, or by a fixedrate. It defines what@zodiacs/engine/vedic's userAyanamsa defines, with its epoch given as any instant in a request is.
