19 Apr 2006: Since observations in different wavebands are sensitive to different sizeddust grains, multi-wavelength imaging of debris disks provides a valuable observational test of modelswhich explain structure seen in sub-mm observations ... This has the potential

19 Apr 2006: To test the sensitivity of the model fits to the assump-tion of astronomical silicates, we also fit the radial pro-files using amorphous carbon grains (ρ = 1.85 ... grains. TheMIPS and SCUBA observations are then distinctly dif-ferent grain populations.

28 Sep 2006: After ingestion tothe archive, an initial series of quality control (QC) tests re-ject sub-standard data before the catalogues across differentbands are merged. ... Following commissioning of WFCAM, a few nights (ap-proximately 10 hours per survey) were

6 Jan 2006: Tests using a larger aperture (4 arcsecond diameter) for the calculationof the zeropoint show no difference. ... We think this is an important test of the 2MASS-based calibration.

26 Jan 2006: These patterns are still being assessed, although a series of tests using a higher order r5 term showed some improvement. ... A series of tests using the UKIRT FS observations to monitor the WFCAM 2MASS calibration are being carried out, with very

2 Nov 2006: In the following tests we have used the 2MASS PSC as the basis for all the astrometry. ... After a few tests it became clear that not only had we got the sign wrong in the predicted value for the distortion (easy to do) but also the magnitude of

17 Jan 2006: Tests on real WFCAM data (the UDS test data, see Section 6) showed that a more detailed model was required. ... 7 Crowded field tests. Tests have been carried out using data covering M17 in order to test the performance in more crowded fields.
