RGS

These flags indicate conditions which cast serious doubt upon the quality of the event as an X-ray detection:

• ON_BADPIX

  At least one pixel included in the event is found in the bad pixel table.

• NEXT_TO_BADPIX

  The pixel under the event centroid shares an edge with a pixel from the bad pixel table.

• ON_WINDOW_BORDER

  The pixel under the event centroid lies in the first or last row or column of the telemetered window.

• BELOW_ACCEPTANCE

  The calibrated energy of every pixel included in the event lies below the acceptance threshold.

• BAD_SHAPE

  The event does not lie entirely within a two-by-two pixel region.

• ON_NODE_INTERFACE

  The pixel under the event centroid shares an edge with the oposing node.

These flags provide information about the composition of the event:

• ON_NODE0

  At least one pixel included in the event lies in node zero.

• ON_NODE1

  At least one pixel included in the event lies in node one.

• ONBOARD_SER

  At least one pixel included in the event represents an on-board reconstruction.

• FLICKERING This event is due to a flickering pixel.
