"Attributes\n----------\n"
"The attributes on UVCal hold all of the metadata and data required to\n"
"work with calibration solutions for interferometric data sets. Under the\n"
"hood, the attributes are implemented as properties based on\n"
":class:`pyuvdata.parameter.UVParameter` objects but this is fairly\n"
"transparent to users.\n\n"
"UVCal objects can be initialized as an empty object (as ``cal = UVCal()``).\n"
"When an empty UVCal object is initialized, it has all of these attributes\n"
"defined but set to ``None``. The attributes can be set by reading in a data\n"
"file using the :meth:`pyuvdata.UVCal.read_calfits` or\n"
":meth:`pyuvdata.UVCal.read_fhd_cal` methods or by setting them directly on\n"
"the object. Some of these attributes are `required`_ to be set to have a\n"
"fully defined calibration data set while others are `optional`_. The\n"
":meth:`pyuvdata.UVCal.check` method can be called on the object to verify\n"
"that all of the required attributes have been set in a consistent way.\n\n"
'Note that objects can be in a "metadata only" state where\n'
"all of the metadata is defined but the data-like attributes (``gain_array``,\n"
"``delay_array``, ``flag_array``, ``quality_array``) are not. The\n"
":meth:`pyuvdata.UVCal.check` method will still pass for metadata only\n"
"objects.\n\n"
"Note location type attributes (which are given in topocentric xyz\n"
"coordinates) have convenience properties named the same thing with\n"
"``_lat_lon_alt`` and ``_lat_lon_alt_degrees`` appended through which you can\n"
"get or set the values using latitude, longitude and altitude values in\n"
"radians or degrees and meters.\n\n"
