Usage of findRADec
Return to directory of Todd's CASA extensions
Takes an image and converts an RA, Dec value into pixel coordinates. See also
findPixel, which is the inverse function.
Usage
au.findRADec(image, radec='', round=True, getvalue=False, beam=None)
- round: round the pixels to the nearest integer
- getvalue: if True, then print the pixel value
- beam: if not None, and getvalue==True, then interpret this as the FHWM beam in arcsec, assume the image is in MJy/sr, and compute the Jy/beam at this pixel
Example:
CASA <9>: au.findRADec('IN_VEX220.LINE_hann.image','17:20:55.3 -35:45:01',round=True)
Out[9]: (189, 407)
