Notes: a. These lines must precede those that follow. Optional control lines MUST be used in listed order b. c (continuation) control lines may be used directly after bdfin, hklin, remove, and/or hkl lines to allow more data items to be entered than will fit on one line. |

Notes: a. Rejected reflections may be listed by entering the line reset psta 4 b. See the ADDREF section of the ADDREF program description. c. If the nolp option is chosen, 1/Lp will be excluded from the output bdf unless it is copied from input by an explicit or implied bdfin instruction. |

Notes: a. For data conversion types itof2 , itof , f2toi , and ftoi , the 1/Lp calculation method is automatically set to rlp2 ; otherwise, it is set to none . b. Fields 4 and 5 are only for 1/Lp calculation methods rlp3 and rlp4 . |
transf [a] [b] | 1-9 | transformation matrix a11,a12, a13, a21, a22, a23,a31, a32, a33 | |
Notes: a. The transformation is: h'k'l' = hkl*a-matrix b. As of 3.7.2 the transf command was modified to reject reflections that transform to fractional indices. This can be used in conjunction with the ADDREF oabs to retain (untransformed) only those reflections which would have been rejected by the transformation. They can then be viewed with GIP for instance. |

Notes: a. The default for each quantity is such that, effectively, no restriction is made. If the nmax option has been specified in the ADDREF line, the limits line quantities will be ignored. |

Notes: a. Exception: h, k, and l each take three fields on the hkl line, but are specified using the one mnemonic hkl on the hklin line. The use of continuation, c, lines with hkl and hklin input lines is allowed but there must be a one-to-one correspondence between the data on the hklin-c pair and the hkl-c pairs. |
