TimeJD¶

class astropy.time.TimeJD(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source]¶

Bases: TimeNumeric

Julian Date time format. This represents the number of days since the beginning of the Julian Period. For example, 2451544.5 in JD is midnight on January 1, 2000.

Attributes Summary

`cache`	Return the cache associated with this instance.
`in_subfmt`
`jd1`
`jd2`
`jd2_filled`
`mask`
`masked`
`name`
`out_subfmt`
`precision`
`scale`	Time scale
`subfmts`
`value`	Return time representation from internal jd1 and jd2.

Methods Summary

`mask_if_needed`(value)
`set_jds`(val1, val2)	Set internal jd1 and jd2 from val1 and val2.
`to_value`([jd1, jd2, parent, out_subfmt])	Return time representation from internal jd1 and jd2.

Attributes Documentation

cache¶: Return the cache associated with this instance.

in_subfmt¶

jd1¶

jd2¶

jd2_filled¶

mask¶

masked¶

name = 'jd'¶

out_subfmt¶

precision¶

scale¶: Time scale

subfmts = (('float', <class 'numpy.float64'>, None, <ufunc 'add'>), ('long', <class 'numpy.float128'>, <function longdouble_to_twoval>, <function twoval_to_longdouble>), ('decimal', <class 'numpy.object_'>, <numpy.vectorize object>, <numpy.vectorize object>), ('str', <class 'numpy.str_'>, <numpy.vectorize object>, <numpy.vectorize object>), ('bytes', <class 'numpy.bytes_'>, <numpy.vectorize object>, <numpy.vectorize object>))¶

value¶: Return time representation from internal jd1 and jd2. Subclasses that require parent or to adjust the jds should override this method.

Methods Documentation

mask_if_needed(value)¶

set_jds(val1, val2)[source]¶: Set internal jd1 and jd2 from val1 and val2. Must be provided by derived classes.

to_value(jd1=None, jd2=None, parent=None, out_subfmt=None)¶: Return time representation from internal jd1 and jd2. Subclasses that require parent or to adjust the jds should override this method.
