| | 57 | * 17:15 EAM: We only have a single (r-band) flat for gpc2. I had been lying to the system in camera.config to pretend that all filters (eg, g.00002) were in fact r-band. this allowed all images to be processed, albeit with a sub-optimal flat. However, we have known for a while that psastro uses this wrong value (r) to select the reference stars. It also seems to mess up MOPS somehow. To get around this problem, I have registered the chips for the single flat as each of g,i,z,y,w flats as well. I have therefore stopped lying to IPP in gpc2/camera.config, so hopefully this will allow MOPS to get better photometry starting tonight. |
