Annotation of the 'common' data-file format for diffraction instruments
____________________________________________________Numor 16500 below is a typical file for an omega:x-theta scan on D10.
With the q-scan this is the most frequently occurring 'type' of data file of D10, but other 'types' may be generated, e.g. from simple acquisitions or inelastic scans.
The format has been common with the other single-crystal diffractometers, D9, D15 and D19 since 25 March 1989. The location of data in all groups of fields except the last is invariant. The variation that may occur in the last is simply in the number of data per point in addition to the count (or many counts for a multidetector), monitor and time.
Summary of file format:

Information from G. McIntyre, November 1994
INDIFD is a Fortran callable routine for reading uncompressed data and may be found in /usr/ill/lib/indifd.o
This instrument offers very high neutron intensity at the sample, which, coupled with the large multi-detector, offers the possibility of performing a wide range of measurements at high precision, or with short measuring times (stroboscopic/cyclic/kinetic measurements).
Three similar data formats reflect these different types of measurements. All have the same basic header information. In the simplest case the format is 80A 480A 30F 25F 30F 15F 55F 15F + 1 x ( 1600J ) The headers (80A 480A 30F 25F 30F 15F 55F 15F) are as follows:

Notes:
a) Motor Parameters
These are TH1 (15), TH2 (15) and OM (11), taken from the file MOT. Not all can
be modified or listed by MAD. Numtries1 and Numtries2 are the actual number of
attempts made to position in the external positioning loop for motors TH1 and
TH2.
b) Boum!
These six parameters (in degrees) are derived from others. BeamLo1, and BeamH1
designate the limits of the main beam which the detector1 must avoid, similarly
for the second detector, BeamLo2, Beamhi2.
MinBoum is the difference in angle between the two detectors to avoid
collisions (typically 30, 45 or 60 degrees), and MaxBoum is the largest
angle permitted between the two arms (to avoid the coders being caught in
a pincer action).
c) Monochromator
The twelve parameters (stored in the IN1 files) cannot be changed by MAD on
D4. There are six rotation/translation values for the monochromator turret,
and translation, together with their corresponding zero-offsets.
d) Slits and Filters
These are at present set manually by the user. The slits and sample-detector
distances, SD1, and SD2 are used to calculate the BOUM! factors. The slits
have coders, which read in mm/100, but are not at present computer readable.
The three filter flags correspond to the cadmium, iridium, or rhodium filters
being in use, or not.
e) Reactor parameters, Lohengrin
The reactor power is recorded together with the status of Lohengrin (PN1)
which can interfere with D4 when it is operating in certain modes.
f) Detector voltages
The anode and cathode voltages are recorded for the each detector.
g) Sample environment
Tsample (K) Tcontrol (K) Tambient (K) Pfourreau (tr) Pcollim (tr)
Pcloche (tr) Pcryo (tr) Ioven (A) TCtype
Five additional voltages are recorded
Voltage1 (V) Voltage2 (V) Voltage3 (V) Voltage4 (V) Voltage5 (V)
h) Other parameters
Wavelength (A) added by hand (typically 0.3, 0.5 or 0.7A)
ScanType Four possibilities: 1 (scan TH1), 2 (scan TH2), 3 (scan THE (both))
4 (scan Omega (detectors fixed)
SD1, SD2 the permitted values are 728, 1455, or 2910mm.
Trig M(1)/T(2) indicates whether the scan duration is based on time or flux.
Det (1,2 or 3) indicates whether detector 1 or 2 is operational, or both (3)
Delta(deg) a fourth motor when in use.
Note:
Certain parameters cannot at present be entered in the data. At
present these values are set to -0.66666600E+06.
