#1559 Jython TSB which doesn't return data with time axis should be trimmed to requested time

[Jeremy Faden]

Ivar had a dataset in his script that would link BMag and R, which are both time series with TSB. The result is also a TSB, but it is not trimmed, and he would see several orbits' worth of data on his half-orbit plots.

I am reminded of this bug when using the mash-up tool to look at DST vs Kp. It always shows six months, even if the timerange is just one month.

Try the mash up script: vap+inline:dst=getDataSet('vap+cdaweb:ds=OMNI2_H0_MRG1HR&id=DST1800&timerange=2015-12-06+06:09+to+2016-02-02+20:24')&kp=getDataSet('vap+cdaweb:ds=OMNI2_H0_MRG1HR&id=KP1800&timerange=2015-12-06+06:09+to+2016-02-02+20:24')&kp=synchronizeOne(dst,kp)&link(dst,kp)&timerange=July+2016

And advance to Aug 2016. Notice nothing changes.

Said another way:

tr= 'Aug+2016'
ds= getDataSet("vap+inline:dst=getDataSet('vap+cdaweb:ds=OMNI2_H0_MRG1HR&id=DST1800')&kp=getDataSet('vap+cdaweb:ds=OMNI2_H0_MRG1HR&id=KP1800')&kp=synchronizeOne(dst,kp)&link(dst,kp)&timerange="+tr)
kp= ds.property(QDataSet.DEPEND_0)
tt= kp.property(QDataSet.DEPEND_0)
print extent(tt)

This prints "2016-07-01 00:00 to 2016-12-31 23:00"...

I'm putting in an experimental trimToTsbRange function that will trim the data when there are rank 1 timetags found within the data.

This appears to work without causing any new problems.
