CSP - NTT/SOFI Exposure Times

Date of last modification: Mar. 16 2009, 1:00 pm chilean time.


                     Supernovae  (sorted by local time of observation)

Exposure times are given as AB cycles x individual exposure times (DIT) x repetitions (NDIT)

SN finding charts can be found HERE and/or HERE. 


Exposure times are only tentative and need to be
adjusted according to resulting S/N. 

Procedure:

Observe the SNe using one mode (blue or red), followed by a telluric standard selected from the list of Hipparcos G stars.
SN and standard should be observed as close in airmass as possible.
Use this tool to find standard stars closest in airmass for a given SN coordinate and observing LST.

Repeat the same procedure with the other (red or blue) mode.

The list of telluric standards can also be found at ESO/ISAAC pages.

See more instructions in the CSP procedures page.
