readHDUs :: ByteString -> Either String [HeaderDataUnit] Source #
Parse and read all HDUs in the input string
readPrimaryHDU :: ByteString -> Either String HeaderDataUnit Source #
Parse and read only the Primary HDU from the input string
getKeyword :: Text -> (Value -> Maybe a) -> HeaderDataUnit -> Either String a Source #
Look up a keyword and parse it into the expected format
getHDU :: String -> Int -> [HeaderDataUnit] -> Either String HeaderDataUnit Source #
Get the HDU at an index and fail with a readable error
