added cube support for view method in ds9 #102

Closed sosey closed 7 years ago

sosey commented 7 years ago

cube arrays can now be loaded using the view() method in DS9. If there are 3 dimensions, the cube dialog will open automatically in DS9.

import numpy as np
import imexam
rancube = np.ones([50, 50, 50]) * np.random.rand(50)
a=imexam.connect()
a.view(rancube)
a.zoom()
a.close()

It could be made more general. Right now it support 2 and 3 dimensional arrays, need to figure out the better way to support (y,x,z,n) arrays like this: 

Filename: test_cube.fits
No.    Name         Type      Cards   Dimensions   Format
0    PRIMARY     PrimaryHDU     215   ()
1    SCI         ImageHDU        13   (1032, 1024, 35, 5)   int16
2    REFOUT      ImageHDU        13   (258, 1024, 35, 5)   int16

@stscieisenhamer pull it down and give it go!

Chooses the wrong axis, at least compared to fits_load. Data is located in:

/grp/jwst/ssb/eisenhamer/miriteam/cube.fits

And I tried loading the data both using datamodels.open and astropy.io.fits with the same results.
