lcdata.HDF5Dataset

class lcdata.HDF5Dataset(path, meta)

Dataset corresponding to an HDF5 file on disk.

This class only loads the metadata by default. Accessing a light curve in the dataset will read it from disk.

Typically you won’t want to use this class directly. Instead, call lcdata.read_hdf5 with in_memory set to False to read a file.

Parameters

• path (str) – Path to the file.

• meta (Table) – Metadata table.
