Notes.

(a)

The X-ray bursts observed by Insight-HXMT are listed without numbers.

(b)

We only use the last two digits to represent NICER ObsIDs, so x = 42022001, y = 52022001, and z = 46390101.

(c)

The peak rates with persistent emission being subtracted were measured from the 1 s light curves in the energy range of 0.5–10 keV.

(d)

The bolometric peak flux of each burst is in units of 10−8 erg s−1 cm−2.

(e)

The bolometric touchdown flux is in units of 10−8 erg s−1 cm−2.

(f)

The observed recurrence time.

(g)

The time of burst onset to its peak.

(h)

The decay time of bursts defined as the ratio of the burst fluence to its peak flux.

(i)

The ratio of the integrated persistent flux to the burst fluence, respectively.

(j)

The tail of burst #3 was truncated due to a data gap.

(k)

Burst #16 was observed in the UFA file.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
