Function Documentation

main()

int main	(	int	argc,
		char *	argv[]
	)

This program generates a camera data sequence from FITS data files.

The input FITS files are converted in a sequence of camera pictures saved in ROOT files. A list of FITS files must be provided. The following assumptions are made about the format of these files:

• The list of HDUs is scanned: the first image HDU is considered (XTENSION = IMAGE).
• The number of axes must be exactly 3 (NAXIS = 3)
• The first axis is considered as the Y axis of the camera.
• The second axis is considered as the Z axis of the camera.
• The third axis is considered as the time coordinate separating pictures.
• The "BITPIX" is considered to be the image bit resolution. It should not exceed 16 bits.
• Each image is separated by the camera time resolution (given in argument)
• The time of the first image is set to T0 (given in argument).

The files are read sequentially. For each of them a ROOT file is produced in the current direvctory. Camera pictures are saved using the Camera class.

Note

Use snl-picture-play.cc to replay the pictures in the resulting ROOT files.

Parameters

[in]	argc	Number of arguments.
[in]	argv	List of arguments.
