NAME std_blue.prg

VERSION 1.8

SYNTAX MIDAS

CALL

from $DFS_PRODUCT/BIAS_RED/$DATE:
uves.MeasureQuality -a <AB> -c std_blue.prg [-i|--NOingestQC1pars]
where

<AB> is the Association Block

[-i] forces QC1 parameter ingestion (default)

[--NOingestQC1pars] prevents QC1 parameter ingestion

INSTRUMENT UVES

RAWTYPE STD_ECH_BLUE & STD_ECH_BLUE_WS

PURPOSE Comparison of raw, master and/or reference STD_ECH_BLUE files for UVES QC assessment; QC1 values are calculated and fed into the QC1 table. QC1 plot(s) and/or display(s) are generated, and later reviewed within certifyProducts.
The generated plots stored in $DFO_PLT_DIR/$DATE with the name r.<DPid>_tpl_0000.fits.png where <DPid> is the Data Product Identification of the first frame of the template.

PROCINPUT RAW frame; INSTR_RESPONSE_BLUE, EFFICIENCY_TABLE_BLUE, WCALIB_FF_RESPONSE_BLUE & RED_STANDARD_BLUE products

std_ech_blue_ws.montage.png
A montage image made up of the following individual reports simply for the purposes of easier/better display in XV during the certification process. Created together with the reference montage (see below) within the uves.MeasureQuality script. Can be recreated manually by calling the script uves.makeQCreportMontage -a <AB>, see uves.makeQCreportMontage -h for more details.
std_ech_blue_ws.montage.ref.png
A montage image made up from the individual QC reports of the reference AB located by the script uves.getRefAB. During certification, the two montage images are blinked to facilitate identification of unusual features. This reference montage created at the same time as the AB montage (see above).The montage of the reference AB is easily identified during the blinking as the one with the grey background.
std_ech_blue_ws_0000.fits.png
plot 1:traces across the middle row and column of the RAW frame
plot 2:cross order profile
plot 3:the chromatic response taking the response at the blaze maximum of each order over the the full wavelength range.
plot 4:the efficiency plotted order by order. The blaze function is clearly seen. The single representative efficieny of the frame is represented by the blue filled circle.
plot 5:histogram of pixel values in the RAW frame.
plot 6:histogram of response curve

ALGORITHM

Description of algorithms:
Algorithms for pipeline created keywords are (in principal) described in the pipeline user's manual

mean_raw: mean level of raw file, this QC parameter is currently calculated by the QC report script, not by the pipeline.
Description: simple statistical mean of a central region of the RAW image.
mean_resp: mean level of response curve, this QC parameter is currently calculated by the QC report script, not by the pipeline.
Description: mean response computed with the MIDAS command:
```
stat/ima <PRO.CATG=INSTR_RESPONSE_BLUE> + exc=1,450 bins=1
```
lambda_min: minimum wavelength [Angstrom], this QC parameter is computed by the pipeline, product keyword CRVAL1.
lambda_max: maximum wavelength [Angstrom], this QC parameter is currently calculated by the QC report script, not by the pipeline.
Description: computed from the PRO.CATG=INSTR_RESPONSE_BLUE product as:
```
lambda_max = START(1)+STEP(1)*NPIX(1)
```
where the image descriptors START, STEP and NPIX have their usual meaning in MIDAS BDF images.
n_order: number of orders, this QC parameter is currently calculated by the QC report script, not by the pipeline.
Description: derived from the number of columns in the PRO.CATG=EFFICIENCY_TABLE_BLUE product, i.e. equalent to NAXIS2
max_effic: efficiency value at wave_c, this QC parameter is currently calculated by the QC report script, not by the pipeline.
Description: maximum of the efficiencies at the center of each blaze of each order
wave_c: central blaze wavelength [Angstrom], this QC parameter is currently calculated by the QC report script, not by the pipeline.
Description: wavelength at which the maximum efficiency is measured.
ins_temp4_mean: average temperature inside air [C], this QC parameter is taken directly from the header of the first RAW file, it propagates to the PRODUCT file(s) unchanged by the pipeline, product keyword INS.TEMPi.MEAN.
airmass: average airmass during exposure, this QC parameter is taken directly from the header of the first RAW file, it propagates to the PRODUCT file(s) unchanged by the pipeline, product keyword TEL.AIRM.START+TEL.AIRM.END.

CERTIF

Reasons for rejection:

Too little light
saturation
