The Proceedings will be published by ESA's Publications Division (EPD) some 3 months after the meeting, as Special Publication SP-493. Authors should submit their  hardcopy camera-ready papers to the ESA Editor at the Symposium; electronic  input is NOT accepted. To allow this rapid publication and a homogeneous presentation, please prepare your paper as follows:

• Use any word-processing software, and preferably a laser printer.

· Paper format: standard A4 (21 x 29.7 cm) or U.S. letter size (8 ½ x 11 inches)
· Use only one side of the paper
· Vertical typing area is 24 cm (for A4 this means a top margin of 3 cm, bottom 2.7 cm)
· Horizontal typing area is 17 cm (for A4 this means left & right margins of 2 cm each)
· Text in two columns of 8 cm width each, separated by a centre interval of 1 cm
· Justified text, using Times Roman 10 points; single line space (11 points).
 
• At the top of the first page, to be centred:

· the TITLE (in 11 pt bold CAPITAL letters)
· the Author's Name(s) (in mixed case)
· the Author's affiliation and professional address (with phone/fax numbers and email).
 
•  Start the text (in the left column) with an abstract of about 150 words.

 
• Figures and photographs will be printed in black and white (NOT colour). Remember

that detail and contrast are lost in printing, so please ensure the illustrations are of
good quality and contrast.
