NIRES uses an IDL based quicklook tool.
( QL ).
Spectroscopy QL
This QL has some tabs that have the following uses:
- The Math tab for operations with images such as sdiff (subtracts
the previous image from the current image), arithmetic
operations, photometry, and bias and flat-field correction.
- The Plot tab for plotting options such as profile cuts (vertical, horizontal, and diagonal)
and also Gaussian fits. Note that the Gaussian fit option allows
the observer to move the telescope so that the slit goes to the
Gaussian centroid. The slitang calculation has not been
implemented yet.
- The Tel tab for telescope moves between two points (Move
Telescope) or from a point to a predefined slit center (Slit center). The scam PA and slit PA
options have not been implemented.
In addition, while there are no images being taken (no gois or goiv)
the following python commands can be used:
dv n1 n2
This command will subtract slit viewing camera
image number n2 from image number n1 and display
the n2-n1 image. If only one argument is given then the script
displays that image number. The script only needs the image number
as it completes the image name based on the current observing root
filename. Example: dv 4 3 will display image v190212_0004.fits minus
v190212_0003.fits if today is Feb 12, 2019.
ds n1 n2
This command will subtract spectroscopy image n2 from n1 and display
the n2-n1 image. If only one argument is given then the script
displays that image number.
