Templates description

This template allows simple preset at given coordinates and position angle. Both the chopping angle and chopping amplitude could be different as in the science template, but we advise you against it as it increases unecessarily the overheads. The template allows for guiding and simple tracking mode.

TIMMI2_img_acq_MoveToPixel

This template allows to position the source at a user-defined position of the chip. The other functionnalities are the same as for the simple preset acquisition template. The reference pixels have been set to (135,95) because the standard imaging mode is "smallsource".

TIMMI2_spec_acq

This template allows to position the object on the slit at a user-defined Y-position along the slit. An extra flag for observation type is propose for archiving and calibration purposes: science object or standard star. If the object is to faint to be seen on a single chopped image, the acquiistion should be done as follow: take a series of exposure using either of the imaging template, compute the offset from the object on detector to the slit position (e.g. 164,110 for 1.2" slit ), then request the TIO to perform a blind telescope offset and start observing with the spectroscopic template. However, P2pp will report an error if your observing template does not include an acquisition template, hence ALWAYS include the spectroscopy acquisition temaple in your OB.

TIMMI2_img_obs_classic

This template reproduce the original TIMMI2 classic observation: the NOD throw is opposite to the chopping direction. The positive position of the second NOD position corresponds to the negative position of the first NOD position. Hence the NOD throw is not user-defined but exactly the opposite to the Chop Throw.

TIMMI2_img_obs_smallsource

This template is the standard imaging template, and is designed for compact objects. The NOD throw is user-defined. We strongly advise the user against using a NOD throw larger than 40arsec (in RA/DEC) to avoid loosing the guide star. This template is not using combined offsets. The offsets are defaulted to 10 arcsec around the center of the detector.

TIMMI2_img_obs_jitter

This templae is very similar to the smallsource template. The NOD throw is replace by the possibility for the user to enter a series of jitter positions and a number of exposures. The number of exposures and jitter offset do not necessarily have to match. The template will execute as many offsets as there are exposures. E.g. if the number of exposure is smaller than the number of offsets, the template will only execute as many offset as there are exposures; if the number of exposure is larger than number of jitter offsets, the template will execute all offsets, then restart the offset sequence untill the number of exposure is reached. The each offset is relative to the previous one.

TIMMI2_spec_obs

This is the spectroscopic template: the functionalities are the same as for the template TIMMI2_img_obs . The nodding is NOT user defined and is exactly the opposite to the chop throw.

TIMMI2_spec_obs

This is the spectroscopic template: the functionalities are the same as for the template TIMMI2_spec_obs . We have added an extra feature: a thruslit image at the beginning of the spectrum exposure to check on the alignment of the slit with the object: the thruslit image is taken with the N1 filter (not optional). For faint object, the normal spectroscopic template should be used. The functionalities are the same as the TIMMI2_spec_obs template.
