Time at next rise/set of ``target``.
Parameters
----------
t : `~astropy.time.Time` or other (see below)
Time of observation. This will be passed in as the first argument to
the `~astropy.time.Time` initializer, so it can be anything that
`~astropy.time.Time` will accept (including a `~astropy.time.Time`
object)
target_name : str
'moon' or 'sun'
location : `~astropy.coordinates.EarthLocation`
Observatory location
prev_next : str - either 'previous' or 'next'
Test next rise/set or previous rise/set
rise_set : str - either 'rising' or 'setting'
Compute prev/next rise or prev/next set
location : `~astropy.coordinates.EarthLocation`
Location of observer
horizon : `~astropy.units.Quantity`
Degrees above/below actual horizon to use
for calculating rise/set times (i.e.,

For a predicative adjective, returns the attributive form (lowercase).
In German, the attributive is formed with -e, -em, -en, -er or -es,
depending on gender (masculine, feminine, neuter or plural) and role
(nominative, accusative, dative, genitive).

Returns a new Constraint from the given string.
Uppercase words indicate either a tag ("NN", "JJ", "VP")
or a taxonomy term (e.g., "PRODUCT", "PERSON").
Syntax:
( defines an optional constraint, e.g., "(JJ)".
[ defines a constraint with spaces, e.g., "[Mac OS X | Windows Vista]".
_ is converted to spaces, e.g., "Windows_Vista".
| separates different options, e.g., "ADJP|ADVP".
! can be used as a word prefix to disallow it.
* can be used as a wildcard character, e.g., "soft*|JJ*".
? as a suffix defines a constraint that is optional, e.g., "JJ?".
+ as a suffix defines a constraint that can span multiple words, e.g., "JJ+".
^ as a prefix defines a constraint that can only match the first word.
These characters need to be escaped if used as content: "\(".

Return True if the given Word is part of the constraint:
- the word (or lemma) occurs in Constraint.words, OR
- the word (or lemma) occurs in Constraint.taxa taxonomy tree, AND
- the word and/or chunk tags match those defined in the constraint.
Individual terms in Constraint.words or the taxonomy can contain wildcards (*).
Some part-of-speech-tags can also contain wildcards: NN*, VB*, JJ*, RB*
If the given word contains spaces (e.g., proper noun),
the entire chunk will also be compared.
For example: Constraint(words=["Mac OS X*"])
matches the word "Mac" if the word occurs in a Chunk("Mac OS X 10.5").
