#Adding colums to hudl app verification#
More about verification inĪstropy will be discussed in a later chapter. The example below is flagged by such verification. To the FITS standard (e.g., for testing purposes), the omstring()Ĭards can be verified with Card.verify(). If the user wants toĬreate a card with a customized format or even a card which is not conforming To the FITS standard and has a fixed card image format. The Card() constructor will check if the arguments given are conforming In other words, once a card is created, it is created for a specific, immutable Card ( 'OBSERVER', 'Hubble', 'string value' ) > print ( c1 ) print ( c2 ) print ( c3 ) print ( c4 ) print ( c5 ) # show the cards TEMP = 80.0 / temperature, floating value DETECTOR= 1 MIR_REVR= T / mirror reversed? Boolean value ABC = (2.0, 3.0) / complex value OBSERVER= 'Hubble ' / string valueĬards have the attributes. Card ( 'ABC', 2 + 3 j, 'complex value' ) > c5 = fits. 'mirror reversed? Boolean value' ) > c4 = fits.

Card ( 'DETECTOR', 1 ) # comment is optional > c3 = fits. Card ( 'TEMP', 80.0, 'temperature, floating value' ) > c2 = fits. There is usually nothing gained by manually using aĬard object, except to examine how a card might appear in a headerĪ new Card object is created with the Card constructor: Card objects are just wrappersĪround such tuples that provide the logic for parsing and formatting individualĬards in a header. (keyword, value, comment) tuple as an argument can also take aĬard object as an argument. In fact, most Header methods that accept a (keyword, value) or Header object, and it is not necessary to directly manipulate cards. Most of the time the details of dealing with cards are handled by the There are also special kinds of cards:Ĭommentary cards (see above) and card images taking more than one 80-columnĬard image. Return - in a FITS file’s storage format. Physically, it takes 80 columns (bytes) - without carriage A card image in a FITS header consists of a keyword name, a value, and
