Create A New FITS File

• File name: If a full path is not specified, the file will be created in the current directory (as shown in the open file dialog box).
• Data Type: The basic data types are
  • Byte : bitpix = 8
  • Integer : bitpix = 16
  • Long : bitpix = 32
  • Float : bitpix = -32
  • Long Long : bitpix = 64
  • Double : bitpix = -64
  The first 3 can be either Signed or Unsigned. BSCALE and BZERO keywords will be created to produce the non-standard Signed Byte and Unsigned Integer and Long data types.
• Dimensions: Provide the size of the array with a comma- or space-separated list of its dimensions. For example, a 3-dimensional image could be specified with "10 20 30", producing in image with dimensions of 10x20x30.
