; NAME:
;       TYKW_MVALID_INT
;
; PURPOSE:
;       This function is to get the information if the data is valid or not
;       from the observation interuption info

;
; INPUTS:
;       timej: structure array with 'time internal format'.
;       d0pa: structure of the 0p0a data of the specified frequency
;
; OPTIONAL INPUT KEYWORDS:
;
; OUTPUTS:
;       mvalid: 1-dimensional byte array
;               if 1 the data is valid
