- DW, (dwell time) is the time step used in the digitilization in units of microseconds (1/sampling rate) (e.g. of FID)
- NS, (number of scans) number of repetition of experiment
- NBLK, (number of blocks) how many shots/blocks (e.g. FIDs) were recorded in one experiment
- BS, (block size) number of points in one shot/block (e.g. FID)
- BINI, time step of the first block in units of seconds
- BEND, time step of the last block in units of seconds
- watch out: BINI and BEND can contain a string instead of a float number. It has to be evaluated (e.g. BEND = '5 * T
- BGRD, is the grid of the time steps (lin, log or list)
- TIME, start time of experiment
- BRLX, relaxation field of the experiment (variable for the dispersion)
