Purpose of this page:
- Provide photometry references for Herschel specific photometry
Contents
Aperture Photometry Parameters
| Filter | Aperture Radius (") | Inner Sky Radius (") | Outer Sky Radius (") | Aperture Correction |
|---|---|---|---|---|
| 70 microns | 9.6 | 9.6 | 19.2 | 0.7331 |
| 100 microns | 9.6 | 9.6 | 19.2 | 0.6944 |
| 160 microns | 12.8 | 12.8 | 25.6 | 0.6602 |
APT parameters
| Parameter/Setting | SHIPs value | Comments |
|---|---|---|
| Aperture Values | As in above table recomputed to pixels. | |
| Select source algorithm | Model 0 | |
| Select sky algorithm | Model B | |
| Use centroid in photometry calculation? | Yes. Box is checked. | |
| Automatically snap aperture to centroid? | Yes. Box is checked. |
Photometry Assignment
The Big Picture
- Gather relevant and previously available photometry on NGC 281 (DONE, except Spitzer)
- Gather images from previous surveys (DONE)
- Herschel Images (DONE, but may be reprocessed)
- Aperture Photometry
- PSF photometry (Preliminary version, calibration missing).
- Check Aperture photometry for bad sources, missed sources.
- Create flags for all sources.
- Check Aperture vs. PSF photometry. Select one or the other for each protostar.
- Finalize Herschel photometry
- Merge all photometry.
