Burst Data Export

In addition to the basic burst quantities listed in the Exported Burst Data table, it is possible to export derived quantities (using algebraic expressions involving those basic quantities or user-defined aliases). This is done on the right side panel, which can be shown or hidden by pressing on the ellipsis (...) or double-arrow button (<<) on the top right corner of the window:

Additional quantities of interest can be entered in the Burst Statistics table.

Note that basic statistics which have not been computed prior to exporting (such as the average or max count rates, for instance) will have values of zero.

Exporting Photon IDs, Timestamps and Nanotimes

Checking the Export Photon IDs, Export Timestamps or Export Nanotimes checkboxes create additional ASCII files (named file_name_Photon ID.txt, file_name_timestamp.txt, file_name_nanotime.txt if you have named the primary burst data file file_name.txt) containing the photon IDs, timestamps or nanotimes of each burst as  comma-separated value.

Each file comprises one line per burst, as follows.

Photon ID.txt

p1, p2, p3, p4, ..., pn

where the n p's take the value 0, 1, 2, 3 or 9, with the corresponding meaning:

0: donor excitation, donor emission

1: donor excitation, acceptor emission

2: acceptor excitation, donor emission

3: acceptor excitation, acceptor emission

9: all other photons

Note that the number n of photons for a given burst might be larger than the All_Photons quantity if the file comprises additional channels (such as a Monitor channel, for instance).

Timestamp.txt

T1, T2, T3, T4, ..., Tn

where the n T's are the relative timestamp (in macrotime clock units) of each photon with respect to the first burst photon.

By definition, the first timestamp of a burst is equal to zero.

The absolute timestamp of the first photon can be found in the burst data as its Start Time. 

Nanotimes.txt

t1, t2, t3, t4, ..., tn

where the n t's are the nanotimes (in TAC bin units) of each photon as computed on the Nanotime Display page when pressing on the Compute Photon Nanotimes button. When the nanotime doesn't fall within the user-defined boundaries, the calibrated nanotime is not a number (NaN), which is exported as the special value 65535.
