| Attribute name | Attribute type | Docstring | Unit |
|---|
| combine | str | Type of combination to use {average,median,minmax,sigclip} | |
| fbeam | float | Factor to describe the widening of the beam from the focal plane to photo diode 2. | |
| hsigma | float | High sigma for pixel rejection with sigclip | |
| lsigma | float | Low sigma for pixel rejection with sigclip | |
| merge | int | Merge output products from different IFUs into a common file. | |
| nhigh | int | Number of maximum pixels to reject with minmax | |
| nifu | int | IFU to handle. If set to 0, all IFUs are processed serially. If set to -1, all IFUs are processed in parallel. | |
| nkeep | int | Number of pixels to keep with minmax | |
| nlow | int | Number of minimum pixels to reject with minmax | |
| object_id | oidtype | The object identifier
The object identifier is an attribute shared by all persistent
instances. It is the prime key, by which object identity is established | |
| overscan | str | If this is "none", stop when detecting discrepant overscan levels (see ovscsigma), for "offset" it assumes that the mean overscan level represents the real offset in the bias levels of the exposures involved, and adjusts the data accordingly; for "vpoly", a polynomial is fit to the vertical overscan and subtracted from the whole quadrant. | |
| ovscignore | int | The number of pixels of the overscan adjacent to the data section of the CCD that are ignored when computing statistics or fits. | |
| ovscreject | str | This influences how values are rejected when computing overscan statistics. Either no rejection at all ("none"), rejection using the DCR algorithm ("dcr"), or rejection using an iterative constant fit ("fit"). | |
| ovscsigma | float | If the deviation of mean overscan levels between a raw input image and the reference image is higher than |ovscsigma x stdev|, stop the processing. If overscan="vpoly", this is used as sigma rejection level for the iterative polynomial fit (the level comparison is then done afterwards with |100 x stdev| to guard against incompatible settings). Has no effect for overscan="offset". | |
| recipe_version | int | Version of the recipe | |
| savemaster | int | Save the processed and combined master image before any concolution is done. | |
| savetable | int | Save the table with all the processed pixel values. | |
| temp | float | Lamp temperature [K] used to create the black body function. | |
