TENTATIVE: It's not clear what will be the best way to replace synphot |
|---|
| 3 |
functionality in the pipelines. It could be that adopting an ETC-like |
|---|
| 4 |
model, where pysynphot queries are sent to a server, would be best; or |
|---|
| 5 |
it might be best to pre-calculate the necessary quantities into files |
|---|
| 6 |
that would be managed, thus breaking the dependency on |
|---|
| 7 |
(py)synphot. For purposes of pysynphot planning, we will assume that |
|---|
| 8 |
the pipelines will require this functionality, just in case that is |
|---|
| 9 |
the route that is decided. |
|---|
| 10 |
|
|---|
| 11 |
Purpose of this release: allow pipelines to survive the demise of |
|---|
| 12 |
synphot |

- Provide method(s) on SpectralElement to calculate: |

URESP Flux (in flam) of a star that produces a response |
|---|
| 21 |
of one photon per second in this passband |

- Provide ColorIndex objects so they can be used in the same way as |

| 41 |
SpectralElement objects |
|---|
| 42 |
|
