Notes to the Table 3: ^a Centre position related to the strip map (TDT 29200534); ^b which is along position angle 124 $^{\circ}$ ( $\pm 180$ $^{\circ}$ ) with 150 $^{\prime \prime }$ spacings of 4 individual pointings; ^c the surrounding PDR provides one type of background estimate; ^d TDT 29200534: this position of the strip scan is outside the flow, yet close enough to serve as another reference position for background estimation.
