PESSTO OBs

Night and daytime Calibration

Download the following (updated 20190829, with Version control, these are V1 for ePESSTO and for ePESSTO+)

• • ePESSTO-MASTER-calib_OBs-V1Nov17.tar : the OBs for all EFOSC2 and SOFI day-time lamp calibrations. Added calibrations for gr18 and gr20.

  • ePESSTO+_MASTER-std_OBs-V1Aug19.tar : the OBs for all EFOSC2 and SOFI night-time standard star calibrations

Classification OBs

ePESSTO-MASTER_class_OBs-V1Aug17.tar

These OBs have the 1" slit defined. As discussed in the PESSTO Handbook, if the seeing is <=1.4 then use a 1" slit. If the seeing is >=1.5, then use 1.5" slit.

Comments from Stefano (April 2012) :

• • There is no major gain in using exposures less than 900s ,1500s for faint and very faint. Together with the overhead, one may gain 5 or 10 minutes per object. Considering that we do 50/50 classification and followup, we will not classified more than 10 object per night. Exposing less we could increase to 12, but will result in lower S/N. In April we failed, or struggled to classify about ~1 object per night due to low S/N.

  • On the other hand to improve the S/N significantly we would need to double the exposure time. Which would decreasing from 10 to 5 the classification per night. This is the wrong balance.

  • For relatively bright objects we could use shorter template (for example 300 instead of 600 or 180 instead of 300), but also in this case the gain doesn't seem worthwhile.

Follow-up OBs

Template Science target Follow-up OBs: These are the follow-up OBs for optical spectroscopy and photometry (EFOSC2) and NIR spectroscopy and photometry (SOFI)
