DRAFT DICTIONARY CBF/imgCIF Extensions Dictionary |
Draft version 1.5 for comment |
Definition:
The value of _diffrn_data_frame.details should give a description of special aspects of each frame of data. This is an appropriate location in which to record information from vendor headers as presented in those headers, but it should never be used as a substitute for providing the fully parsed information within the appropriate imgCIF/CBF categories. Normally, when a conversion from a miniCBF has been done the data from '_array_data.header_convention' should be transferred to this data item and '_array_data.header_convention' should be removed.Example:
; HEADER_BYTES = 512; DIM = 2; BYTE_ORDER = big_endian; TYPE = unsigned_short; SIZE1 = 3072; SIZE2 = 3072; PIXEL_SIZE = 0.102588; BIN = 2x2; DETECTOR_SN = 901; TIME = 29.945155; DISTANCE = 200.000000; PHI = 85.000000; OSC_START = 85.000000; OSC_RANGE = 1.000000; WAVELENGTH = 0.979381; BEAM_CENTER_X = 157.500000; BEAM_CENTER_Y = 157.500000; PIXEL SIZE = 0.102588; OSCILLATION RANGE = 1; EXPOSURE TIME = 29.9452; TWO THETA = 0; BEAM CENTRE = 157.5 157.5; ; | Example of header information extracted from an ADSC Quantum 315 detector header by CBFlib_0.7.6.
