Miriad Sanity Tests

  • Generating (from scratch) and displaying an image in miriad:
 % imgen out=map0
 % hexdump -C map0/header | tail
 ...
 000001c0  6e 61 78 69 73 00 00 00  00 00 00 00 00 00 00 08  |naxis...........|
 000001d0  00 00 00 02 00 00 00 02                           |........|


The important thing to note is the last line, if endianism is wrong on your machine, the last 4 bytes might read as 2,0,0,0 instead of 0,0,0,2. Now display the data

 % implot in=map0 device=/xs
 % ds9 &
 % mirds9 map0
  • Getting a dataset from the archive and displaying some basic visibility data
 % wget -O - http://carma-server.ncsa.uiuc.edu:8080/sciarch/data/fringe.3C345.2007feb02.2.miriad.tar.gz | tar zxf -

 % curl http://carma-server.ncsa.uiuc.edu:8080/sciarch/data/fringe.3C345.2007feb02.2.miriad.tar.gz | tar zxf -
 % itemize in=fringe.3C345.2007feb02.2.miriad

   obstype  = mixed-auto-cross
   nwcorr   = 4410
   ncorr    = 66150

   flags      (integer data, 2134 elements)

  • wip: give the following commands to see if you have your environment setup correctly:
 % wip -d /ps
 WIP> box
