| 468 | **
|

| 469 | ** 3. You (the user) may copy and distribute SOFA source code to others,
|

| 470 | ** and use and adapt its code and algorithms in your own software,
|

| 472 | ** distribution that does not consist of intact and unchanged copies
|
|---|
| 473 | ** of SOFA source code files is a "derived work" that must comply
|
|---|
| 474 | ** with the following requirements:
|
|---|
| 475 | **
|
|---|
| 476 | ** a) Your work shall be marked or carry a statement that it
|
|---|
| 477 | ** (i) uses routines and computations derived by you from
|
|---|
| 478 | ** software provided by SOFA under license to you; and
|
|---|
| 479 | ** (ii) does not itself constitute software provided by and/or
|
|---|
| 480 | ** endorsed by SOFA.
|
|---|
| 481 | **
|
|---|
| 482 | ** b) The source code of your derived work must contain descriptions
|
|---|
| 483 | ** of how the derived work is based upon, contains and/or differs
|
|---|
| 484 | ** from the original SOFA software.
|
|---|
| 485 | **
|
|---|
| 486 | ** c) The names of all routines in your derived work shall not
|
|---|
| 487 | ** include the prefix "iau" or "sofa" or trivial modifications
|
|---|
| 488 | ** thereof such as changes of case.
|
|---|
| 489 | **
|
|---|
| 490 | ** d) The origin of the SOFA components of your derived work must
|
|---|
| 491 | ** not be misrepresented; you must not claim that you wrote the
|
|---|
| 492 | ** original software, nor file a patent application for SOFA
|
|---|
| 493 | ** software or algorithms embedded in the SOFA software.
|
|---|
| 494 | **
|
|---|
| 495 | ** e) These requirements must be reproduced intact in any source
|
|---|
| 496 | ** distribution and shall apply to anyone to whom you have
|
|---|
| 497 | ** granted a further right to modify the source code of your
|
|---|
| 498 | ** derived work.
|
|---|
| 499 | **
|
|---|
| 500 | ** Note that, as originally distributed, the SOFA software is
|
|---|
| 501 | ** intended to be a definitive implementation of the IAU standards,
|
|---|
| 502 | ** and consequently third-party modifications are discouraged. All
|
|---|
| 503 | ** variations, no matter how minor, must be explicitly marked as
|

| 504 | ** such, as explained above.
|

| 506 | ** 4. You shall not cause the SOFA software to be brought into
|
|---|
| 507 | ** disrepute, either by misuse, or use for inappropriate tasks, or
|
|---|
| 508 | ** by inappropriate modification.
|

| 509 | **
