Extracting header information

This loads the package

In[1]:=

A FITS image is needed

In[2]:=

In[3]:=

Out[3]=

Here are the entire contents of the above specified FITS image.

In[4]:=

Out[4]=

{SIMPLE {ValueTrue, CommentFITS STANDARD}, BITPIX {Value> ... ; , END {}}

All of the contents of a FITS header, field names and values, are stored as strings.

Here is the value of a specific filed in the above header.

In[5]:=

Out[5]=

A few functions are available that attempt to process the string contents and return numerical results.

option name	default value

Options for parsing dates and times

Here is start time of the image acquisition.

In[6]:=

Out[6]=

option name	default values
ParsingFunction	RAParsingFunction	a function that parses the RA field of the FITS image object.
	DECParsingFunction	a function that parses the DEC field of the FITS image object.
