Authoring FAQ Authoring FAQ

Q: Why won't the authoring tool allow me to observe my object?

A: When you click submit for your observing plan, it is immediately checked for correctness. If the request cannot be carried out for any reason, the submission is rejected. By carrying out this check, the GLORIA system ensures that successful submission is a strong promise of successful execution.

Q: Why does it matter that my "Target is too close to the Sun"?
A: If the target is near to the Sun in the sky, it will only be visible when the Sun is visible (or nearly so). In other words, during daylight! Telescopes designed for night observation are not generally able to deal with daylight, and remain closed during the day (and are often engaged in calibration tasks during dusk and dawn, and therefore
unavailable for ordinary scientific use).
Q: Why doesn't GLORIA recognise my object?
A: GLORIA uses various catalogues to find co-ordinates for a named object. If the name is not in the catalogue, GLORIA doesn't know where to point the telescope. Please check spelling, and then ask for specific help on the forums. But first check the spelling…

Q: I want to observe a particular target using a specific telescope. GLORIA says this is impossible, why?
A: A telescope far in the northern hemisphere (for example) simply cannot see targets deep in the southern
hemisphere – it would have to point down through the Earth to look in that direction. Although targets at the
equator are visible to most telescopes, targets near the poles are not. For a given target, you may not have a free
choice of telescope.

Q: I want to observe a particular target, with a specific target, but GLORIA says the object is below the telescope's horizon, when it clearly isn't! What's wrong?
A: The term telescope horizon refers to how low a telescope can point. This isn't always the true horizontal – the
surrounding skyline is usually not completely flat: there will be buildings, mountains or trees in the way that  block the
line-of-sight. GLORIA has this skyline profile, and will not schedule an observation that goes below the line.

Q: Why is the authoring tool telling me that the constraints are impossible?
A: The authoring tool starts with a list of all available telescopes, and their abilities. Each constraint removes noncompliant telescopes from the list. If no telescopes remain compliant, then obviously there is no way for GLORIA
to carry out the request. The typical solution is to remove all constraints, then re-apply them one at a time, starting
with the most important, and watching how many telescopes remain available.

Q: Can I observe multiple targets in my observing plan?
A: Yes. There is no limit to target commands in the body of the plan
