            TERMOSKAN  CALIBRATION  TABLES


The accompanying set of four tables provides spectral and 
intensity calibration information for the Termoskan 
instrument on the Phobos 2 spacecraft. The tables show the 
spectral filter response of the Termoskan visual and 
infrared channels, the  conversion between data number (DN) 
and brightness for the visual channel, and between DN and 
brightness temperature for the infrared channel. The 
wavelengths in the filter reponse tables are expressed in 
micrometers; the response is given in arbitrary units, with 
a maximum value of 1.00. The visual channel brightness is 
expressed in watts per square meter per steradian; the 
infrared channel brightness temperature is expressed in 
Kelvins.
