Triggering the NOT

1. If the object is visible, call immediately the observing room of the NOT telescope

   
   
2. Use one of the following email templates to execute the observation and modify the

   Dear NOT observer and staff.
   
   This is a trigger of the FRB ToO programme (PI: Daniele Malesani).
   For further details, please see:

   Please reply to frb@dark-cosmology.dk to acknowledge the reception
   of this request. The target information and the observing strategy
   are reported below.
   
   Please let us know if you carry out time-critical observations.
   
   For any questions please do not hesitate to contact me on my mobile

   Thank you for your collaboration,

   The purpose of the observation is to obtain a spectrum of the afterglow of
   FRB ??????. Please execute these observations as soon as
   possible. [Please execute these observations around ?? UT when
   the object becomes visible at the NOT.] [If the afterglow is bright
   enough we may ask for a spectrum to be taken.]
   
   A finding chart and a visibility plot are attached to this message.
   
   ------------
   
   The object is localised to the following position:
   
   RA(J2000) = < ***** COORDINATE ***** >
   Dec(J2000) = < ***** COORDINATE ***** >
   Current uncertainty radius = < ***** ERROR RADIUS ***** >
   
   We ask for an initial imaging observation followed by the spectroscopic
   observation
   
   The commands to run the scripts are [TRIGGER PERSON: add
   FRB name, coordinates, and delete the appropriate instrument
   command]:
   
   Go to ~obs/scripts/53-032
   
   And execute
   
   tcs.enter-object FRB?????? hh mm ss ±deg mm ss 2000 0 0 0
   
   ./too-alfosc-photometry.sh FRB?????? R,100,1
   
   For more information on the various command options:
   
   http://www.not.iac.es/observing/too/P53/P53-032/photo_alfosc.html
   
   If the afterglow is brighter than approximately R = 21 then please
   obtain 3 x 1800 s spectra by executing the following commands
   [TRIGGER PERSON: add FRB name]:
   
   ./too-alfosc-spectroscopy.sh FRB?????? Grism_#4 Slit_1.3 60 1800 3
   
   Note: to estimate if the afterglow is bright enough, please look
   at the finding chart (link provided above) where magnitudes of a
   few objects in the field-of-view are listed. We will of course also
   inspect the images and assist in taking this decision.

   For calibration we request [TRIGGER PERSON: edit accordingly]:
   
   Spectroscopy
   
   - Observation of a spectrophotometric standard star with the same setup
   close to the FRB position
   
   [TRIGGER PERSON: modify GRISM and SLIT]:
   
   - 5 flat field images (./too-alfosc-spec-flat.sh GRISM SLIT 5)
   
   - 10 bias frames
   
   Please ensure that all the calibration data are transferred to
   our FTP account by activating remsave before the calibration data
   are obtained:
   
   rempath /data/service/calib
   remsave_on
   
   When the calibration files have been acquired, please turn off remsave:
   
   remsave_off
