Estimated Total Execution Time (hours, including overheads)

General Description
The goal of the observation is 1) to monitor the spectroscopic variation of CO 4.7 um band, and 2) to perform spectro astrometry of the band. At the submission of the OBs, we have encountered an error saying that "although the check mark of the AO guide star being the target itself is on, the two coordinates differ more than certain amount", or something like this. we checked the coordinate again, and found the numbers are same. in order to get the OBs checked in, we turn of the check-mark temporarilly. but in reality, THE TARGET IS THE AO GUIDE STAR. We have SINFONI runs, 281.C-5031 (A-C), meant to be executed with the CRIRES observations. because of the monitoring nature of the programme, it would be nice to have two observations done simultaneously, but if it decreases the chance that the OBs are actually executed, we prefer the CRIRES and the SINFONI OBs actually executed in the non-simultaneous manner to being not executed at all. but if the two obsevations are executed in the same night, namely, 281.C-5031 (A) of SINFONI with 281.C-5031 (D) of CRIRES together in the same night, and (B) with (E), and (C) with (F), we would greatly appreciate. if the mismatch of the execusion time is a few hours, it is totally acceptable, and greatly appreciated. The finding chart made from 2MASS Ks is attached, but the observation will be acutally done in M-band.
Waiver Requests
We request the waiver to use the non-standard free grating setting with the reference wavelength 4730.0 nm. this is to match the wavelength coverage to the spectrum observed in last April. The request has been granted.
Critical Observing Condition Constraints
The spatial resolution is important for the observation. having cirrus is fine, but the good seeing condition like 0.8-1.0s is necessary.
Time-Critical Aspects
The one of the goals of the observation is to monitor the spectral variation of the EX Lupi at the 4.7 um CO emission bands. We have three runs, D, E, and F, and requested that the runs are distributed so that the interval of the each run is at least 2 days. we hope, the all three runs will be done within 2 weeks (the interval of the first run to the last fun), but a few days of longer interval is no problem. We have SINFONI runs, 281.C-5031 (A-C), meant to be executed with the CRIRES observations. because of the monitoring nature of the programme, it would be nice to have two observations done simultaneously, but if it decreases the chance that the OBs are actually executed, we prefer the CRIRES and the SINFONI OBs actually executed in the non-simultaneous manner to being not executed at all. but if the two obsevations are executed in the same night, namely, 281.C-5031 (A) of SINFONI with 281.C-5031 (D) of CRIRES together in the same night, and (B) with (E), and (C) with (F), we would greatly appreciate. if the mismatch of the execusion time is a few hours, it is totally acceptable, and greatly appreciated.
Special Execution Requirements
Special Calibration Information
We picked up HR 6508 as the spectroscopic standard star. The star is meant to be observed after the observation of EX Lupi, when the airmass of the standard star is about same with thta of the object at the time of its observation. We have checked 2MASS images of the region, and found it is the only bright star seen in the field of view 50"x50" with the spatial resolution of 2MASS. The expected S/N at 4723nm without sky in single exposure is 150. The expected S/N after total observation of the calibration star is ~200. The spectral type of HR 6508 is B2IV. Allowed spectral range for atmospheric standard star is AO or earlier.
ToO Information
ToO Activators List
Do the README file and the instrument comments of the telluric stars OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral type and allowed spectral range?
Do any OBs include wavelength or flatfield calibrations?
N/A
If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?
N/A
If the slit viewer guide star is different from the target, are the RA and DEC offsets accurate to within 0.05 arcsec and do they take into account the relative proper motion between the two objects?
N/A
If you have preferences which OBs should be executed first for objects at similar RA, did you make use of the User Priority field in the OBs?
