Dear Anita,
many thanks for your comments on the Source Catalogue DM. Most of them
are being taken into account in the ongoing production of the first
document draft. I detail hereby a few exceptions - as well as some more
qualitative additional comments:
- the "Source Catalogue DM" aims indeed at being - as you wish -
"source-centered". Its overall rationale is to isolate elements which
belong to, e.g., external models such as "Observations" or "SED", and
put link to the relevant models. Hence, I have moved "snr" and
"detectionProbability" to "SED" and "Observations", respectively, as
you suggest. I am open and keen to do the same if further "duplicated
items" are spotted
- the "AGN" box is indeed a "Classification"-type box, and will be
renamed accordingly. As such, it is intended to be neatly separated
from the "Morphology" box, which should contain only purely
observational properties, as you suggested
- although a simple logical flag to highlight orbiting objects is
surely a possible solution, I am not sure I understand why the "Orbit"
element should make any harm. I have left it as it was in the original
scheme, waiting for more discussion on this point.
- I am not sure I understand your suggestion to substitute
"varAmplitude" with "d(flux)/d(time)". "d(flux)" is
"varAmplitude", if I understand correctly what you mean. On the other
hand, "d(time)" can be often misleading, as it may be related to the
observation sampling rather then to the intrinsic variability timescale
of the source. I have left it as it was in the original scheme, waiting
for more discussion on this point. I have left as well "varPeriod" and
"varType", which look to me unambiguous, and therefore worth being
included in the model
- it goes without saying that many - if not most - of the
quantities in the model are wavelength-dependent. We have
"Source.frequency", in facts
- is "limiting noise" the same as "localBackgroundNoise"? I guess
so. In this case, I believe that it is more appropriate to leave it in
the "Observation" box
Regards, Matteo
