+# FITS Definitions
+
+# The FITS standard readable by the FITS reader using these definitions:
+# 
+# 1.  8 bits / byte
+# 2.  ASCII character code
+# 3.  MII integer data format (i.e. 8 bit unsigned integers and 16 and 32
+#     bit signed twos complement integers with most significant bytes first.)
+# 4.  IEEE 32 and 64 bit floating point format
+#
+#
+# The following deviations from the FITS standard are allowed:
+# 
+# 1. The number of FITS bytes per record is normally 2880 or up to 10 times
+#    2880 bytes but may be arbitrarily specified  by the user.
