astropy.io.fits.hdu.image:ImageHDU.__init__
source: /astropy/io/fits/hdu/image.py :1192
Signature
def __init__ ( self , data = None , header = None , name = None , do_not_scale_image_data = False , uint = True , scale_back = None , ver = None ) Summary
Construct an image HDU.
Parameters
data: arrayThe data in the HDU.
header: `~astropy.io.fits.Header`The header to be used (as a template). If
headerisNone, a minimal header will be provided.name: str, optionalThe name of the HDU, will be the value of the keyword
EXTNAME.do_not_scale_image_data: bool, optionalIf
True, image data is not scaled using BSCALE/BZERO values when read. (default: False)uint: bool, optionalInterpret signed integer data where
BZEROis the central value andBSCALE == 1as unsigned integer data. For example,int16data withBZERO = 32768andBSCALE = 1would be treated asuint16data. (default: True)scale_back: bool, optionalIf
True, when saving changes to a file that contained scaled image data, restore the data to the original type and reapply the original BSCALE/BZERO values. This could lead to loss of accuracy if scaling back to integer values after performing floating point operations on the data. Pseudo-unsigned integers are automatically rescaled unless scale_back is explicitly set toFalse. (default: None)ver: int > 0 or None, optionalThe ver of the HDU, will be the value of the keyword
EXTVER. If not given or None, it defaults to the value of theEXTVERcard of theheaderor 1. (default: None)
