Figure 1: 2-25 keV X-ray lightcurves for the four non-PRE multi-peaked bursts in the RXTE archive for 4U 1636-536. Burst numbers (1)-(4) are burst numbers 40, 48, 56 and 111 respectively in the burst catalogue of Galloway et al. (2007). PCU refers to the RXTE Proportional Counter Units. The burst modelled in Bhattacharyya & Strohmayer (2006a) is burst (3); that in Bhattacharyya & Strohmayer (2006b) is burst (4). |

Figure 2: Dimensionless persistent flux (as a fraction of the Eddington rate) against colour-colour diagram coordinate Sz for X-ray bursts from 4U 1636-536, data from the RXTE burst catalogue (G07). Sz is assumed to be proportional to accretion rate. Single peaked bursts are shown as diamonds, and the four multi-peaked non-PRE bursts by squares. Bursts (1)-(3) from Fig. 1 cluster together; Burst (4) sits alone. |

Figure 3: The distribution of multi-peaked bursts (shaded) with Sz compared to other bursts for the three sources in the RXTE catalogue that have a) non PRE multipeak bursts and b) trace out a long enough path in the colour-colour diagram to calculate Sz. These sources are 4U 1636-536, Aql X-1 and 4U 1608-52. The lower panel shows the distribution compared to all other bursts, the upper panel the distribution compared to PRE bursts. |

Figure 4: Burst fluence against accretion rate as measured by Sz (data taken from G07). Diamonds: single peaked non-PRE bursts; Asterisks: PRE bursts; Squares: multi-peak non PRE bursts. Error bars are similar in size to the diamonds. |
