Observations with EFOSC2 the all night.


Seeing ~ 0.6" during the all night.

EFOSC2 biases + arcs / dome flats + spec.pol calib + skyflats grz

For spectro-polarisation, the centre of the central hole is (x,y) = (1034,987)

UT 00:47  HD-10038      spectro-polarisation test

Alignement problem. The star is at y=1054. No signal through the mask hole. 

UT 01:10  SN2012dy      gr16

UT 02:27  STD vma2      gr11 + gr13 + gr16 / slits 1.0" and 5.0" (S. Smartt)

UT 02:52  LSQ12gdj      gr11 + gr16

UT 03:39  HD-13588      spectro-polarisation 

With the TO and the advices from Stefan we finally understood 

how to do it. The right template to use is MoveToPixel instead of 

MoveToSlit to properly put the star in the mask hole.

UT 03:51  HD-42078      spectro-polarisation 

UT 04:02  HD-10038      spectro-polarisation 

UT 04:21  LSQ12gpw      gr11 + gr16

UT 05:14  LSQ12hqs      gr13 *classification*: no target

There is nothing at the target position (even on a V=80s exposure image)

UT 05:53  SQ12hnj       gr11 + gr16

UT 06:36  LSQ12hng      gr13 *classification*: idem, no target 

UT 06:38  LSQ12hon      gr13 *classification*: SN Ia z=0.18 around max (SNID)

UT 06:39  STD gd71      gr11 + gr13 + gr16 / slits 1.0" and 5.0" 

                        + 1 exposure slit 1.0" with no grism

UT 07:09  LSQ12hnr      gr13 *classification*: SN Ia z=0.13 (0.005) age=-2.5d (SNID)

UT 07:26  LSQ12hml      gr13 *classification*: cannot find the target;

                        finding chart with half of the field missing... 

UT 07:36  LSQ12hns      gr13 *classification*: AGN ???? or reduction problem ?

UT 07:58  LSQ12htu      gr13 *classification*: SN IIb z=0.037 (SNID)

UT 08:29  STD LTT3864   gr11 + gr13 + gr16 / slits 1.0" and 5.0"

UT 08:51  HD-97689      spectro-polarisation

EFOSC2 skyflats grz

As a general remark, it could be more efficient if, for each detected

new transient, we wait for it to appear on at least two epochs

separated by at least one day (and not 3 minutes) before pushing the

target in the PESSTO marshall "classification queue". That way the NTT

observers will not waste the telescope allocated time looking for non

existent objects...
