title: re-sizing a fits image in python
body: <p>I have 5 astronomy images in python, each for a different wavelength, therefore they are of different angular resolutions and grid sizes and in order to compare them so that i can create temperature maps i need them to be the same angular resolution and grid size.</p>
  
  <p>I have managed to Gaussian convolve each image to the same angular resolution as the worst one, however i am having trouble finding a method to re-grid each image in python and wondered if anyone knew how to go about doing this? </p>
  
  <p>I wish to re-grid the images to the same grid size as the worst quality image and so i can use that as a reference image if required. Thank you</p>
