This can be used to directly load tables from the Internet. For example, Vizier tables from the CDS:: >>> table = ascii.read("ftp://cdsarc.u-strasbg.fr/pub/cats/VII/253/snrs.dat", ... readme="ftp://cdsarc.u-strasbg.fr/pub/cats/VII/253/ReadMe") If the header (ReadMe) and data are stored in a single file and there is content between the header and the data (for instance Notes), then the parsing process may fail. In this case you can instruct the reader to guess the actual start of the data by supplying ``data_start='guess'`` in the call to the ``ascii.read()`` function. You should verify that the output data table matches expectation based on the input CDS file. **Using a reader object** When ``Cds`` reader object is created with a ``readme`` parameter passed to it at initialization, then when the ``read`` method is executed with a table filename, the header information for the specified table is taken from the ``readme`` file. An ``InconsistentTableError`` is raised if the ``readme`` file does not have header information for the given table. >>> readme = "data/vizier/ReadMe" >>> r = ascii.get_reader(ascii.Cds, readme=readme) >>> table = r.read("data/vizier/table1.dat") >>> # table5.dat has the same ReadMe file >>> table = r.read("data/vizier/table5.dat") If no ``readme`` parameter is specified, then the header information is assumed to be at the top of the given table. >>> r = ascii.get_reader(ascii.Cds) >>> table = r.read("data/cds.dat") >>> #The following gives InconsistentTableError, since no >>> #readme file was given and table1.dat does not have a header. >>> table = r.read("data/vizier/table1.dat") Traceback (most recent call last): ...
