I. Naming the file.
-------------------

Use the following convention:

Lastname_Wavelength_um_2013-MM-DDc.tbl

Where,
Lastname = Your last name (or your teachers's last name)
Wavelength = Either 70, 100 or 160 
um = The shorthand for microns
2013 = The year
MM = Month in two number integer, e.g. 06
DD = Day in two number integer, e.g. 09
c = A character starting with 'a' to denote multiple versions.


II. Header
----------

Use '#' character to start each header line.
Place the following information in header.
# NGC 281 and filter in um
# Author of the data table = YOU
# Aperture Radius in pixels (identify the units)
# Sky annulai in pixels (identify the units)
# Aperture correction
# Equinox of reported coordinates.
# Source of notes.  I.e. who wrote the notes/comments.
# One blank line.
# Names of columns
# Units of columns

Example header

# NGC 281 100um
# Author: Babar Ali
# Aperture radius = 8 pixels
# Sky annulai = 8, 16 pixels
# Aperture correction = 0.86
# Coordinates are in J2000.0
# Comments by Babar Ali
# 
# ID, ra,    dec,   Flux,......
#   ,(deg), (deg),  (Jy),


III. List and order of columns.
-------------------------------

Use comma ',' to deliminate columns.

(1) ID  an integer number.  Format i3.3
(2) RA a floating point number. Format f12.9
(3) Dec a floating point number.  Format f12.9
(4) Raw Flux, as measured in APT.  Format f9.3
(5) Error on Flux.  Use 0.00 for now.  Format f9.3
(6) Aperture corrected Flux.  Format f9.3
(7) Background Flux.  Format f9.3
(8) Source Flag.  1 = point source, 0 = not, -1 = Maybe.  Format i2
(9) FWHM of source in pixels.  Format f7.2
(10) Multiplicity flag.  # of sources within aperture.  Format i2
(11) Spatial location.  1=East, 2=West, 0=Neither or indenterminate, Format i1
(12) Comments
