; NAME:TMP2BYTE
;	
; PURPOSE:
;      To return the byte value of a temperature.
;	
; CATEGORY:
;	
; CALLING SEQUENCE:
;      TMP2BYTE(cam,temp)
;
; INPUTS:
;      CAM: A one byte INTEGER, specifying the camera number.
;      
;      TEMP: A SCALAR or ARRAY of temperatures.
;	
; KEYWORD PARAMETERS:
;      None.
;
; OUTPUTS:
;      BYTE: An INTEGER array, containing the byte values      
;            corresponding to the temperatures passed in
;            TEMP.
;      	
; COMMON BLOCKS:
;      None.
;	
; SIDE EFFECTS:
;      None.
;
; RESTRICTIONS:
;      None.
;
; PROCEDURE:
;      The slope, m, and intercept, b, needed to produce the
;      linear transformation from the temperature to its
;      byte representation (note the parameters are different
;      for camera 0 and 1)is calculated. This transformation
;      is then applied to the values in TEMP and returned in
;      BYTE.
