Mask pixels are set true(=1) if the corrected count/frame is less than ratethreshold. ratethreshold in (0:1) Name of the dataset to which the mask image/cube is written. Input style, either evlist or image. Name of the input event list dataset. Name of the input image dataset. Lower energy boundary for the input image in keV. evlo in (0:) Upper energy boundary for the input image in keV. evhi in (0:) True if the input image consists of single-pixel events only. Output style, either sky or raw. If raw, the output format is FITS cube. Template image set for output. If inputstyle=image, the file specified by imageset is used, regardless of the user-specified value of templateset. Attitude style: either binnedset or template. Binned attitude set name. Minimum averaged count of the threshold to process a frame. avcnttoprocess in (0:) True if the count/frame image is also output. Name of the dataset to which the rate/frame image/cube is written. True if the approximate form of the pattern fraction parameters is used. Flip the sign of the boresight euler%psi. This parameter should be removed after the boresight is fixed.
