NDF2DST

Converts an NDF to a Figaro (Version 2) DST file

Description:

This application converts an NDF to a FIGARO (Version 2) ‘DST’ file. The rules for converting the various components of a DST are listed in the "Notes". Since both are hierarchical formats most files can be be converted with little or no information lost.

Usage:

ndf2dst in out

Parameters:

IN = NDF (Read)

Input NDF data structure. The suggested default is the current NDF if one exists, otherwise it is the current value.

OUT = Figaro (Write)

Output Figaro file name. This excludes the file extension. The file created will be given extension ".dst".

Examples:

ndf2dst old new

This converts the NDF called old (in file old.sdf) to the Figaro file new.dst.

ndf2dst spectre spectre

This converts the NDF called spectre (in file spectre.sdf) to the Figaro file spectre.dst.

Notes:

The rules for the conversion are as follows:


NDF		Figaro file	Comments

Main data array	$\Rightarrow$	.Z.DATA
Imaginary array	$\Rightarrow$	.Z.IMAGINARY
Bad-pixel flag	$\Rightarrow$	.Z.FLAGGED
Units	$\Rightarrow$	.Z.UNITS
Label	$\Rightarrow$	.Z.LABEL
Variance	$\Rightarrow$	.Z.ERRORS	After processing
Quality	$\Rightarrow$		It is not copied directly though bad values indicated by QUALITY flags will be flagged in .Z.DATA in addition to any flagged values actually in the input main data array. .Z.FLAGGED is set accordingly.


NDF		Figaro file	Comments

Title	$\Rightarrow$	.OBS.OBJECT

AXIS(1) structure	$\Rightarrow$	.X
AXIS(1) Data	$\Rightarrow$	.X.DATA_ARRAY	unless there is a DATA component of AXIS(1).MORE.FIGARO to allow for a non-1-dimensional array
AXIS(1) Variance	$\Rightarrow$	.X.VARIANCE	unless there is a VARIANCE component of AXIS(1).MORE.FIGARO to allow for a non-1-dimensional array
AXIS(1) Width	$\Rightarrow$	.X.WIDTH	unless there is a WIDTH component of AXIS(1).MORE.FIGARO to allow for a non-1-dimensional array
AXIS(1) Units	$\Rightarrow$	.X.UNITS
AXIS(1) Label	$\Rightarrow$	.X.LABEL
AXIS(1).MORE.FIGARO.xxx	$\Rightarrow$	.X.xxx
			Similarly for AXIS(2), …, AXIS(6) which are renamed to .Y .T .U .V or .W

FIGARO extension:
.MORE.FIGARO.MAGFLAG	$\Rightarrow$	.Z.MAGFLAG
.MORE.FIGARO.RANGE	$\Rightarrow$	.Z.RANGE
.MORE.FIGARO.SECZ	$\Rightarrow$	.OBS.SECZ
.MORE.FIGARO.TIME	$\Rightarrow$	.OBS.TIME
.MORE.FIGARO.xxx	$\Rightarrow$	.xxx	recursively

FITS extension:
.MORE.FITS
