_compute_hdu_checksum(self, data, sum32=0)

This code should only be called with blocks of 2880 bytes Longer blocks result in non-standard checksums with carry overflow Historically, this code was called with larger blocks and for that reason still needs to be for backward compatibility.

Translated from FITS Checksum Proposal by Seaman, Pence, and Rots. Use uint32 literals as a hedge against type promotion to int64.

Examples

See :

Local connectivity graph

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
