| Version | Release Notes |
| 2.12.0 | Support for NICMOS/NCS: new calibration files, automatic selection of calibration files |
| 2.11.0 | Ported to IDL 5.4 |
| 2.8.0 | New weighting, adjustment of trace, plotting of reponse on top of spectrum, interactive adjustment of offsets, marking of object on grism images. |
| 2.7.0 | New calibration files. |
| 2.6.5 | A few fixes, better error handling added. |
| 2.6.0 | Supports correction for intra-pixel response function for
point sources. |
| 2.5.10 | NICMOSlook can now read the same kind of input LIST
of images as Calnic~C. There is also some limited support for moving objects. |
| 2.5.7 | NICMOSlook can now read FITS spectral tables produced by Calnic-C 2.5.7 or later.. |
| 2.5.5 | Improved the implementation of the WCS based registration. WARNING: The format of the order.conf file in the CALIB directory has changed an d is not compatible with previous versions of NICMOSlook or Calnic-C. |
| 2.5.4 | A few minor bug fixes |
| 2.5.2 | Now properly uses the WCS to compute the coodinates of a spectra in the grism frame based on the position of the object in the direct images. Pixels sizes are assumes to be the same, but the image sizes do not need to be identical. |
| 2.5.1 | Fixes a problem whereby NICMOSlook did not properly detect that a different grism definition should be loaded when loading another grism image that was taken with a different grism |
| 2.5.0 | Supports extraction of any spectral order. |
| Can either mark or extract a particular spectral order through the use of the file order.conf in the $NICMOSLOOK_BASE/calib directory | |
| Properly avoid regions occupied by all the spectral order spectra (Those that are not explicitely set to be ignored) when estimating the backgound using linear interpolation | |
| Object list now includes RA and DEC of objects. These are read back in and take precendent over the x,y pixel coordinates in the object list if FROMWCS is set to 1 in calnicc.setup. | |
| 2.3.7 | New response curves added w/ error bars. |
| 2.3.6 | Minor fix to enable IDL 4.0 compilation |
| 2.3.5 | Type of extraction reported now corresponds to the option selected by the user. |
| 2.3.4 | New flatfields setup. Now uses nref format flatfields |
| 2.3.3 | Minor bug fix release |
| 2.3.2 | Reads and displays Calnic-C and NICMOSlook spectra FITS tables. |
| Fixed crash when trying to plot Strips in Log mode | |
| Fixed crash when the Automatic Size options was used on too many objects | |
| Added a feature to save a spectrum to an ASCII file (additionally to PS and FITS table) | |
| Added parameter POS_ERR to estimate the error (in pixel) in the position estimates of objects in the direct image (Used to compute final spectral error bars). | |
| 2.3.1 | New weights computed and integrated in the calib directory. |
| Color was added to the spectral plots | |
| Keyword UNITS was added to the FITS table header | |
| Parameter PUNITSW added to calnicc.setup to set the default units to use when displaying/outputting spectra. | |
| Added Bkg Sub status to the spectral plots | |
| Selecting the position of an object with the cursor causes the centroid of this approximate region to be computed and selected. | |
| 2.3.0 | New wavelength solutions, flux calibration, and background estimates for G096 and G141 now integrated in the calib directory. |
| Spectra are now properly calibrated in DN/s, mJy, or Erg/cm^2/s. | |
| OBJECT_KEY in fitskeywords.dat defines the name to use on the actual plots. | |
| Nw option to use DTQ info to ignore some bad pixels |
