writeto(filename, data, header=None, output_verify='exception', overwrite=False, checksum=False)
        
        File to write to. If opened, must be opened in a writable binary mode such as 'wb' or 'ab+'.
data to write to the new file
the header associated with         data
. If :None:None:`None`, a header of the appropriate type is created for the supplied data. This argument is optional.
Output verification option.  Must be one of         "fix"
,         "silentfix"
,         "ignore"
,         "warn"
, or         "exception"
.  May also be any combination of         "fix"
 or         "silentfix"
 with         "+ignore"
,         +warn
, or         +exception" (e.g. ``"fix+warn"
).  See         astropy:verify
 for more info.
If         True
, overwrite the output file if it exists. Raises an         OSError
 if         False
 and the output file exists. Default is         False
.
        overwrite
 replaces the deprecated         clobber
 argument.
If :None:None:`True`, adds both         DATASUM
 and         CHECKSUM
 cards to the headers of all HDU's written to the file.
Create a new FITS file using the supplied data/header.

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
