merlin.formats.aux(x, y, locations, dates_fn, specmap, chipmap)[source]¶

Builds aux formatted timeseries.

Parameters:	x – x projection coordinate of chip y – y projection coordinate of chip locations – chip shaped 2d array of projection coordinates dates_fn (fn) – returns dates that should be included in time series specmap (dict) – mapping of keys to specs chipmap (dict) – mapping of keys to chips
Returns:	A tuple of tuples.

The aux format key is `(chip_x, chip_y, x, y)` with a dictionary of sorted numpy arrays representing each spectra plus an additional sorted dates array.

>>> aux(*args)
    (((chip_x, chip_y, x1, y1), {"dates":   [], "nlcd": [],
                                 "nlcdtrn": [], "trends": [],
                                 "mpw":     [], "dem": [],

                                 "slope":   []}),
     ((chip_x, chip_y, x1, y2), {"dates":   [], "nlcd": [],

merlin.formats.pyccd(x, y, locations, dates_fn, specmap, chipmap)[source]¶

Builds inputs for the pyccd algorithm.

Parameters:	x – x projection coordinate of chip y – y projection coordinate of chip locations – chip shaped 2d array of projection coordinates dates_fn (fn) – returns dates that should be included in time series specmap (dict) – mapping of keys to specs chipmap (dict) – mapping of keys to chips
Returns:	A tuple of tuples.

The pyccd format key is `(chip_x, chip_y, x, y)` with a dictionary of sorted numpy arrays representing each spectra plus an additional sorted dates array.

>>> pyccd_format(*args)
    (((chip_x, chip_y, x1, y1), {"dates":  [],  "reds": [],
