The IDL (Interactive Data Language)8 package can read the binary dump files. A simple procedure for reading athena1.0 binary dumps is included in athena1.0/vis/idl; to run this procedure you will need IDL installed on your system. (Note that binary dumps must be created with the fortran option disabled to be compatible with IDL.) From the athena1.0/bin directory, use the following.
% idl IDL> .run ../vis/idl/pltath.pro IDL> readbin,'Brio_Wu.040.bin' IDL> six_plotA variety of procedures are included in the pltath.pro file, including a procedure to read binary files (readbin), and make simple plots and animations.
