Observations made through the GTN will be used to support several different NASA High-energy Science missions. It is therefore important to ensure that GTN data are taken with a professional level of precision and accuracy. All GTN participants (partners and associates) must therefore be able to demonstrate that they have the requisite skills in data reduction and analysis. If you do not feel that you have the appropriate skills, we invite you to perform the following activities and/or to read through the tutorials. All submissions to the GTN archive will be screened to ensure the quality of the data. Tutorials:
Activities:AGN Surveillance Data AnalysisDescription: Using data already collected by previous surveys determine magnitudes for a GTN program object. Requirements: You must have already passed the basic photometry tutorial as well as completed the AGN education tutorial. Submit a proposal to observe an AGN for long time scale variabilityDescription: The GTN have a list of AGN referred to as the GTN AGN Program Objects. These are several AGN located in the Northern hemisphere that GLAST and the GTN believe to be of special scientific importance. In this activity you will submit a proposal to observe one of these GTN AGN program objects. Requirements: You must have already passed the basic photometry tutorial as well as completed the AGN education tutorial. In addition you must have completed at least one AGN Surveillance Data Analysis activity. Submit a proposal to observe an active galaxy for micro-variabilityDescription: AGN vary on many different scale time scale. Different phenomenon as the core of AGN can cause measurable variability of AGN on the time scale of hours. In this activity you will submit a proposal to observe and analyze the micro-variability of a GTN AGN program object. Requirements: You must have already passed the basic photometry tutorial as well as completed the AGN education tutorial. In addition you must have completed at least one AGN Surveillance Data Analysis activity. Gamma-ray Burst Astrometry AnalysisDescription: An important part of gamma-ray burst analysis is quickly determining the location in the sky where the GRB actually occurred. This analysis allows subsequent follow-up observations to be made to future understand the nature of GRBs. In this activity you will compare images taken during a GRB to images of the same field to determine where the GRB occurred. Requirements: You must have completed the astrometry tutorial as well as completed the GRB education tutorial. Gamma-ray Burst Photometry AnalysisDescription: GRBs are temporarily the brightest gamma-ray objects in the sky, but range in brightness in visible light from 9th magnitude to far fainter. The visible light fades rapidly as a function of time following the gamma-ray trigger. When observed promptly (while the gamma-rays are still present), GRBs can be bright enough to be seen by the human eye but in a matter of hours can become too faint to be observed by most small telescopes. Requirements: You must have completed the basic photometry tutorial as well as the GRB education tutorial. |
