AHELP for CIAO 4.13

write_dataset

Context: crates

Synopsis

Write a dataset to an output file.

Syntax

write_dataset(ds, filename, clobber=False, history=True)

Description

Argument Description
ds A CrateDataset object
filename The output file name. To change the format from FITS add a kernel specifier as described in 'ahelp dmopt' and 'ahelp dmascii'.
clobber Set to True if the output file already exists and you wish to over-write it, since the default behavior is to raise an IOError in this case.
history Should the HISTORY and COMMENT records be written out? The default is True.

The write_dataset is used to write out a CrateDataset, and follows ahelp write_file.


Changes in CIAO 4.13

The write_dataset routine is now exported from the pycrates module. In earlier versions of CIAO it was only availabe from the pycrates.hlui module.
