Estimated Total Execution Time (hours, including overheads)

7hours 50minutes

General Description

This is to obtain a high SNR spectrum of the object IRC +10420. Many 30minutes
 exposures are needed. They can be taken on several nights. Also, an attempt to photometrically
 calibrate the spectrum is made by observing 3 stars within 1 degree of IRC+10420.
 If the seeing is less than 2arcsec this may be attempted even in thin cloud conditions.

Special Execution Requirements

The sequence to photometrically calibrate the spectrum of IRC+10420 has
 been designed to be th following : Observe IRC+10420 - standard 1 - standard 2 -
 standard 3 - IRC+10420. This sequence takes less than an hour. The observing blocks
 are flagged with the names : specphot1, specphot2, specphot3, specphot4 and specphot5.
 They should be observed in that order. And please straight after each other.
