IO_SDFITS_WRITER is intended for use by users who wish to write spectral line data to sdfits. See UML for all IO Classes, or IO_SDFITS UML for just the line and continuum sdfits classes.

Routine Summary  10 routines

procedure io_sdfits_writer__define
IO_SDFITS_WRITER is intended for use by users who wish to write spectral line data to sdfits.

procedure IO_SDFITS_WRITER::set_output_file, file_name
Sets the name of the output file, and if the file exists, creates an sdfits object for it

procedure IO_SDFITS_WRITER::set_file, file_name, file_path=string, index_name=string
Sets the file which this object will exclusively be writing to and reading from.

procedure IO_SDFITS_WRITER::nsave_spectrum, spectrum, nsave[, status]
Writes a single spectrum to the sdfits file, saving an NSAVE number in the index file corresponding to this spectrum

function IO_SDFITS_WRITER::get_nsave_index(nsave)

procedure IO_SDFITS_WRITER::overwrite_spectrum, index, spectrum, status=status

procedure IO_SDFITS_WRITER::write_spectra, spectra, file_name=string
Writes given spectra to an sdfits file.

procedure IO_SDFITS_WRITER::set_sprotect_on
Sets index file so nsave numbers cannot be overwritten

procedure IO_SDFITS_WRITER::set_sprotect_off
Sets index file so nsave numbers can be overwritten

function IO_SDFITS_WRITER::get_sprotect()
Retrieves the state of nsave protection

Inherits

io_sdfits_line

IO_SDFITS_WRITER::set_output_file

procedure IO_SDFITS_WRITER::set_output_file, file_name

Sets the name of the output file, and if the file exists, creates an sdfits object for it

Uses

IO::file_exists IO_SDFITS::add_fits_obj

IO_SDFITS_WRITER::set_file

procedure IO_SDFITS_WRITER::set_file, file_name, file_path=string, index_name=string

Sets the file which this object will exclusively be writing to and reading from. Acts much like IO_SDFITS::set_file in the way it forces creation of a new index file

Uses

IO_SDFITS::set_file_path IO_SDFITS_LINE::set_file IO_SDFITS::set_index_file_name IO_SDFITS::free_fits_objs

IO_SDFITS_WRITER::nsave_spectrum

procedure IO_SDFITS_WRITER::nsave_spectrum, spectrum, nsave[, status]

Writes a single spectrum to the sdfits file, saving an NSAVE number in the index file corresponding to this spectrum

Uses

get_nsave_index write_spectra overwrite_spectra

IO_SDFITS_WRITER::get_nsave_index

function IO_SDFITS_WRITER::get_nsave_index(nsave)

Parameters
nsave	.

IO_SDFITS_WRITER::overwrite_spectrum

procedure IO_SDFITS_WRITER::overwrite_spectrum, index, spectrum, status=status

Parameters
index	.
spectrum	.

Keywords
status	.

IO_SDFITS_WRITER::write_spectra

procedure IO_SDFITS_WRITER::write_spectra, spectra, file_name=string

Writes given spectra to an sdfits file. The spectra are translated to their proper form for sdfits, and the rows are written to the output file in extensions based off the data size of each spectrum.

Uses

IO_SDFITS_WRITER::set_output_file IO_SDFITS_WRITER::check_spectrum_size_uniformity IO_SDFITS_WRITER::spectra_to_rows IO_SDFITS_WRITER::write_rows_to_extension IO_SDFITS_WRITER::update_index_with_spectra

IO_SDFITS_WRITER::set_sprotect_on

procedure IO_SDFITS_WRITER::set_sprotect_on

Sets index file so nsave numbers cannot be overwritten

IO_SDFITS_WRITER::set_sprotect_off

procedure IO_SDFITS_WRITER::set_sprotect_off

Sets index file so nsave numbers can be overwritten

IO_SDFITS_WRITER::get_sprotect

function IO_SDFITS_WRITER::get_sprotect()

Retrieves the state of nsave protection

Returns

0 - nsave numbers cannot be overwritten; 1 - they cannot be overwritten
