General Description

NGC 2264 IRS1, also known as Allen's source, is a young, deeply embedded
 YSO. In the NIR, a weak jet-like feature was found, extending from IRS1 to the north.
The star shall be observed using the AMBER and MIDI instruments.

For the MIDI observation, we want to use the GRISM, aiming to measure the visibility
 with good resolution over the N-band.  

No optical counterpart of NGC 2264 IRS1 is known.  Therefore it is necessary to
 use a nearby source for Coude guiding.  A suitable Coude guide star might be OR
 Mon (RA=06:41:09.09, DEC=+09:30:09.6, J2000, V=16.2), separated 40'' from the target.
  An alternative Coude guide star might be V431 Mon (RA=06:41:08.01, DEC=+09:30:40.8,
 V=15.6), which is slightly further away (1.2').

We generated OBs for two calibrator stars to give a backup calibrator in case the
 first calibrator cannot be observed successfully.  Due to the better matching brightness,
 we specify CAL_HD61421 (60 Jy) as our first choice and CAL_HD61935 (8 Jy) as backup
 calibrator star.
