The plots below can be made using their classes in Astro-WISE:

• ReadNoisePlot (astro/plot/ReadNoisePlot.py)
• RawBiasFramePlot (astro/plot/RawBiasFramePlot.py)
• QuickCheckPlot (astro/plot/QuickCheckPlot.py)
• etc.

Usage for all these plots is simply to specify a date range, i.e.:

ReadNoisePlot

awe> p = ReadNoisePlot(date_range=('2011-08-01', '2015-07-01'))
awe> p.make()

QuickCheckPlot

awe> p = QuickCheckPlot(date_range=('2011-08-01', '2015-07-01'))
awe> p.make()

GainPlot

awe> p = GainPlot(date_range=('2011-08-01', '2015-07-01'))
awe> p.make()

Photometric Zeropoints plot (optionally specify filter_name)

awe> p = ZeropointPlot(date_range=('2011-08-01', '2015-07-01'), filter_name='OCAM_g_SDSS')
awe> p.make()

Code: RawDomeFlatFramePlot.py

Code: ZeropointPlot.py (QuickCheckPlusZeropointPlot)

Usage:

awe> q1 = (RawDomeFlatFrame.template.type == 'FLAT,DOME,LIFETEST') & (RawDomeFlatFrame.template.start > datetime.datetime(2011,8,1))
awe> q2 = (PhotometricParameters.template.start > datetime.datetime(2011,8,1)) & (PhotometricParameters.filter.name == 'OCAM_r_SDSS')
awe> p = QuickCheckPlusZeropointPlot(photoms=list(q2), rawdomeflats=list(q1))
awe> p.make()

Quick check domeflats (FLAT,DOME,LIFETEST) counts are placed on the photometric scale using this formula and an arbitrary offset is added (is this correct?: GVK says: yes this is correct.):

-2.5*log10(1/y) + 13.5

• CCD#82 variability seems indeed gone!
