NAME

mkcube -- combine a group of 2D images into an image cube

USAGE

mkcube images cube_image et_gap

PARAMETERS

images

the names of the 2D images to be combined into the cube. These should already have been corrected for positional errors.

cube_image

the name of the cube to be created

et_gap

the etalon gap values to be added to the image header of the cube. If the 2D headers do not contain the gap settings as keyword FPZ, the user must enter the gap values as a string of comma separated values, in either user value (like 500), or instrument values (like 0.5). If the "et_gap" string is NULL (like ""), the 2D image headers will be searched.

verbose = yes

if set to yes, the progress of the operation will be printed.

DESCRIPTION

The 2 dimensional images specified are assumed to be spatially congruent and identical in size. They are added to bands of the cube in the order given, and the gap settings must be entered in the identical order if entered by hand. It is probably best to enter the data in increasing order of wavelength (increasing gap), so that the wavelengths are monotonic.

If the input images are not of pixel type SHORT, they will be converted to SHORTs to save space in the cube.

EXAMPLES

Construct a cube from the 3 images data1, data2, data3 having gaps of 0.220, 0.225, 0.230

cl> mkcube data1,data2,data3 cube 0.220,0.225,0.230
