General Description

This is a ToO projecty aimed to measure the redshift (z) of  a sample
 of 3 X-ray flashes (XRFs). Our final goal is to compare the z distribution of XRFs
 with the one of classical gamma-ray bursts (GRBs). The programme has a granted total
 time of 9 hours, distributed in 4.5 hours at the NTT (equipped with EMMI, Prop.
 ID. 0.76.D-0843(A)) and 4.5 hours at the 3.6m (equipped with EFOSC2, Prop. ID. 
 0.76.D-0483(B)). This readme file refers to the EFOSC2 part of the project (rop.
 ID. 0.76.D-0843(B)).

ToO Information

This is a ToO programme. Our proposal is NOT designed to discover optical
 counterparts of XRFs. Our proposal is just aimed to take spectra of counterparts
 already discovered using other facilities (by us or by other groups).

All the OBs are prepared to perform low resolution longslit spectroscopy. We include
 OBs accounting for 15 EFOCS2 grisms and for five longslit widths (0.7",1.0",1.2",1.5"
 and 2.0").

Finding charts will be submitted at the time of the activation.  Details on the
 slit alignemnt will be also described at the time of triggering. By default all
 the OBs have been set at parallactic angle.

All the OBs  make use of a 2x2 binning.

We have constructed two types of OBs, for 1 hour and for 45 minutes.

No special calibration is required. The default calibration plan is OK for us.

We would appreciate that the data are transferred to us as soon as they are acquired.
 This would allow us to optimize further observations as well as coordinate observations
 with other facilities.
