|

| 4 | This library is derived, with permission, from the International
|
|---|
| 5 | Astronomical Union's "Standards of Fundamental Astronomy" library,
|
|---|
| 6 | available from http://www.iausofa.org.
|
|---|
| 7 |
|
|---|
| 8 | The ERFA version is intended to retain identical
|
|---|
| 9 | functionality to the SOFA library, but made distinct through
|
|---|
| 10 | different function and file names, as set out in the SOFA license
|
|---|
| 11 | conditions. The SOFA original has a role as a reference standard
|
|---|
| 12 | for the IAU and IERS, and consequently redistribution is permitted only
|
|---|
| 13 | in its unaltered state. The ERFA version is not subject to this
|
|---|
| 14 | restriction and therefore can be included in distributions which do not
|
|---|
| 15 | support the concept of "read only" software.
|
|---|
| 16 |
|
|---|
| 17 | Although the intent is to replicate the SOFA API (other than replacement of
|
|---|
| 18 | prefix names) and results (with the exception of bugs; any that are
|
|---|
| 19 | discovered will be fixed), SOFA is not responsible for any errors found
|
|---|
| 20 | in this version of the library.
|
|---|
| 21 |
|
|---|
| 22 | If you wish to acknowledge the SOFA heritage, please acknowledge that
|
|---|
| 23 | you are using a library derived from SOFA, rather than SOFA itself.
