General Description

This is the set of observing templates for the VISIR observations of the
 dusty nova V1280 Sco.

Given our knowledge, the target is probably brighter than 5Jy in all filters. In
 that case, we prefer that the observations to be performed in BURST mode (283.D-5020(D)),
 if possible. If not, the normal mode should be used (283.D-5020(A)).

The calibrator, HD152834, is a M5 star, with a Iras 12micron flux of 8.2Jy. This
 flux is similar to the expected flux of V1280 Sco, and above the 5Jy threshold for
 the burst mode. Therefore, the same calibrator has been chose for the VISIR templates
 A and D.
The target is the brightest of its field.

The observations are challenging: the source is a 0.3" diameter dusty ring. Therefore
 the best spatial resolution is needed to study it (implying good quality burst mode
 observations, and good PSF data too).

Waiver Requests

A Waiver Request was submitted: the burst mode is allowed in service mode.

Moreover, we requested to use templates longer than 1h, and that was agreed.
Nevertheless, we were convinced by some arguments given in the answer to not use
 this priviledge.
