irfpy.mnpi.background
¶
MEX/NPI background proxy module
It provides a getter of background proxy.
The best practice is to use DataCenterMnpiBackground
class as folows.
>>> from irfpy.mnpi import background
>>> dc = background.DataCenterMnpiBackground()
>>> import datetime
>>> tobs, (back, total) = dc.nearest(datetime.datetime(2010, 1, 9, 20, 10))
>>> print(tobs)
2010-01-09 20:10:00.513000
>>> print(back)
4.0
>>> print(total)
143.0
- class irfpy.mnpi.background.DataCenterMnpiBackground[source]¶

(
time array
,bg array
).
>>> import datetime >>> t0 = datetime.datetime(2006, 12, 4) >>> t1 = datetime.datetime(2006, 12, 7) >>> bg = get_background_level(t0, t1) >>> print(len(bg[1])) 1715
