1. Frequently Asked Questions
Q: Are the magnitudes in the ETCs AB or Vega magnitudes? ... Q: How is the signal to noise defined? A: In optical and infrared imaging, the applications display a signal to noise over the PSF area, which is computed in a circle of radius seeing/plate_scale. ... In optical imaging only, a second signal to noise is computed which is the signal to noise at the central pixel. ... A: The template spectra stored in the database are measured or simulated spectra covering different wavelength range. ...

2. Tiny Tim Frequently Asked Questions
Can I use Tiny Tim models in programs like DAOPHOT? This is actually the most frequently asked question. ... Some filters are not included since they are "weird" or cover a range of separate wavelengths, like the linear ramps. ... When Tiny Tim asks for the filter name, just enter "none" or "mono". ... How can I adjust the focus of the Tiny Tim models? ... Can Tiny Tim model the NICMOS coronographic mode? ... What's the deal with the pixel scattering function in WFPC2? ...

... A theory suggests that a certain sub-class of gamma-ray bursts all have the same absolute magnitude. ... The author claims that this absolute magnitude is so different from that in the previous sample that this must belong to a new sub-class of gamma-ray bursts. ... To do this, there needs to be some feature in their spectra which correlates with their absolute magnitude. ...

... 1999: . The largest catalogue of distant powerful radio galaxies, detected with the RATAN-600, mapped in the radio range at the VLA, and photometered in 4 filters at the BTA 6-m telescope was compiled.
