slicing data cube #22

Open wegojobs opened 2 years ago

wegojobs commented 2 years ago

I am having issues with slicing my data cube. With the error, "the sub-cube boundaries lie outside the cube" . I have retried with different radii, but it still gives me the same error. Please someone help.I have been stuck for the last 1 month. Below is the code i am using. from mpdaf.obj import Cube import matplotlib.pyplot as plt plt.ion() cube=Cube(filename='NGC 1097.fits') center=(-30.2837, 41.5688) subCube=cube.subcube(center, 0.1)

It may be a problem with the cube WCS. Can you tell me what is printed out by cube.info() ?

The center you indicate is outside the cube Cube center is 2.77 degree and you ask for 41 degree (center=(-30.2837, 41.5688))
