Tokyo Cabinet <http://tokyocabinet.sourceforge.net/> is a "super hyper ultra
database manager" written and maintained by Mikio Hirabayashi and released
under the LGPL.
Tokyo Tyrant is the de facto database server for Tokyo Cabinet written and
maintained by the same author. It supports a REST HTTP protocol, memcached,
and its own simple binary protocol. This library implements the full binary
protocol for the Tokyo Tyrant 1.1.17 in pure Python as defined here::
http://tokyocabinet.sourceforge.net/tyrantdoc/
Typical usage is with the PyTyrant class which provides a dict-like wrapper
for the raw Tyrant protocol::
>>> import pytyrant
>>> t = pytyrant.PyTyrant.open('127.0.0.1', 1978)
>>> t['__test_key__'] = 'foo'
>>> t.concat('__test_key__', 'bar')
>>> print t['__test_key__']
foobar

class SyntheticCube(object):
'''
SyntheticCube is part the FluxCompensator. It converts
input_arrays (e. g. HYPERION ModelOutput) to "realistic"
synthetic observations (e.g. accounts for PSF, filters & noise).
It contains attributes like ModelOutput (see Notes).
If input_array is already a SyntheticCube object, the attributes are
passed. If input_array is not a SyntheticCube object, SyntheticCube
specific attributes are defined and then passed.
Parameters
----------
input_array : SyntheticCube, ModelOutput, optional
input_array also reads arrays with ModelOutput like properties.
unit_out : str, optional
The output units for SyntheticCube val. Valid options are:
* ``'ergs/cm^2/s'``
* ``'ergs/cm^2/s/Hz'``
* ``'Jy'``
* ``'mJy'``
* ``'MJy/sr'``
The default is ``'ergs/cm^2/s'``.
name : str
The name of the FluxCompensator object until another
input_array is called. The default is ``None``.
Attributes
----------
wav : numpy.ndarray
The wavelengths of val cube slices in microns.
val : numpy.ndarray
The 3D cube with shape (x, y, wav).
units : str
Current units of the val cube.
distance : str
Distance to the observed object in cm.
x_min : float
Physical offset from axis origin in FOV in cm.
x_max : float
Physical offset from axis origin in FOV in cm.
y_min : float
Physical offset from axis origin in FOV in cm.
y_max : float
Physical offset from axis origin in FOV in cm.
lon_min : float
Minimal longitudinal angle.
lon_max : float
Maximal longitudinal angle.
lat_min : float
Minimal latitudinal angle.
lat_max : float
Maximal latitudinal angle.
pix_area_sr : float
Pixel area per sr.
Notes
-----
unit_in : str
Unit of val in input_array. Valid options are:
* ``'ergs/cm^2/s'``
* ``'ergs/cm^2/s/Hz'``
* ``'Jy'``
* ``'mJy'``
* ``'MJy/sr'``
grid_unit : float
Physical unit of FOV axis in cm. Valid options are:
* ``au`` in cm
* ``pc`` in cm
* ``kpc`` in cm
grid_unit_name
Astronomical unit of FOV axis. Valid options are:
* ``'au'``
* ``'pc'``
* ``'kpc'``
FOV : tuple
Tuple ``FOV(x,y)`` of Field of View pixel entries.
* pixel in x direction: ``FOV[0]``
* pixel in y direction: ``FOV[1]``
name : str
The name of the FluxCompensator object until another
input_array is called. The default is ``None``.
stage : str
Gives current operation stage of SyntheticCube.
E. g. ``'SyntheticCube: convolve_filter'``
log : list
List of strings of the previous and current stages.
filter : dict
Dictionary ``filter = {name, waf_0, waf_min, waf_max}``
