### GASP2NDF

Converts an image in GASP format to an NDF

#### Description:

This application converts a GAlaxy Surface Photometry (GASP) format file into an NDF.

#### Usage:

gasp2ndf in out shape=?

#### Parameters:

A character string containing the name of GASP file to convert. The extension should not be given, since ".dat" is assumed.
##### OUT = NDF (Write)
The name of the output NDF.
##### SHAPE( 2 ) = _INTEGER (Read)
The dimensions of the GASP image (the number of columns followed by the number of rows). Each dimension must be in the range 1 to 1024. This parameter is only used if supplied on the command line, or if the header file corresponding to the GASP image does not exist or cannot be opened.

#### Examples:

gasp2ndf m31_gasp m31
Convert a GASP file called m31_gasp.dat into an NDF called m31. The dimensions of the image are taken from the header file m31_gasp.hdr.
gasp2ndf n1068 ngc1068 shape=[256,512]
Take the pixel values in the GASP file n1068.dat and create the NDF ngc1068 with dimensions 256 columns by 512 rows.

#### Notes:

• A GASP image is limited to a maximum of 1024 by 1024 elements. It must be two dimensional.

• The GASP image is written to the NDF’s data array. The data array has type _WORD. No other NDF components are created.

• If the header file is corrupted, you must remove the offending ".hdr" file or specify the shape of the GASP image on the command line, otherwise the application will continually abort.
