ISO-ESO bolometer data: Explanatory Note
_________________________________________



The effective wavelengths, FWHM and zero magnitude fluxes are:

filter  lambda eff	FWHM	Flam,0
	micron		micron	W m-2 nm-1

N	 9.862		5.47	1.29 e-15
N1	 8.328		0.72	2.50 e-15
N2	 9.650		1.57	1.40 e-15
N3	12.774		1.15	4.64 e-16
Q0	18.425		3.23	1.09 e-16	

The zeropoints of the magnitude scale are based on the colours of 
the sun. We have assumed that the two solar analogues in the sample,
HR0098 and HR5459, have colours equal to the solar colours, and from
this assumption we have calculated the magnitudes of HR0098 and HR5459.
All this is described in van der Bliek, Manfroid & Bouchet (1996, A&AS  
119, 547).
