<div class="moz-cite-prefix">Hi Kelle,</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Unfortunately there isn't at the moment
such a recommendation as "TimeSeries data model". </div>
<div class="moz-cite-prefix">There have been several attempts along
the lines of "Cube data model" and Mango but none of these two
data models are a recommendation yet.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">However there is a note proposing a
minimal standardisation for TimeSeries in VOTable here : <br>

<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Basically this note explains how to
describe the time coordinate system by using the <TIMESYS>
element and how to describe the photometric system used for
magnitudes or fluxes with the PhotCal GROUP.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">To implement it you can use the Dachs
framework which as far as I know provides these features.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">All the above relates to TimeSeries
representation.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Data discovery for TimeSeries is
another story.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">You can implement ObsTAP (ObsCore)
services where dataproduct_type = 'tilmeseries'. You can also have
a look to the ObsCore Time extension :
<a class="moz-txt-link-freetext" href="https://github.com/ivoa-std/ObscoreTimeExtension">https://github.com/ivoa-std/ObscoreTimeExtension</a> which is also a
"work in progress".</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Various strategies of data discovery
for TimeSeries are described in this document (ivoa note) :</div>

<div dir="ltr">Hi folks,
<div><br>
</div>
<div>I'm working on wrangling some lightcurves into a "standard"
format. is there a good reference document for a lightcurve
datamodel? At this point, I'm mostly just interested in header
keywords.</div>
<div><br>
</div>
<div>Thanks,</div>
