Sequence of commands to reduce AMBER data

Launch yorick: rlterm yorick
Load the amdlib yorick plugin (once yorick is launched): include,"amdlib.i"
Get help on any yorick or amdlib function: help, [function name]
Quit yorick: quit

Compute the log file: amdlibCreateLog

Load bad pixel map: amdlibLoadBadPixelMap
Show bad pixel map: amdlibShowBadPixelMap

Load flat field map: amdlibLoadFlatFieldMap
Show flat field map: amdlibShowFlatFieldMap

Show the content of a raw data file: amdlibShowRawData, check for the many options that appear on the yorick command line

Compute a P2VM: amdlibComputeP2vm
Same but on a series of P2VM: amdlibComputeAllP2vm
Show a P2VM: amdlibShowP2vm

Compute raw visibilities: amdlibComputeOiData
Same but on a full night: amdlibComputeAllOiData
Show raw visibilities: amdlibShowOiData
Store postscript files of all OI fits files: amdlibShowAllOiData

Average visibilities (including data selection): amdlibPerformFrameSelection. Check the selValue, selType, and selCriterion options in the help of the function
Average a bunch of visibilities: amdlibPerformAllFrameSelection

Build a calibrators diameters database: amdlibGetCalibSize, Here you MUST use the noSearch=1 option as there is NO Internet connexion at the school network. At home, without this option, it will seach for online calibrators catalogs to fill-in the ~/amdlibCalibDatabase.txt file
Compute the transfer function: amdlibComputeTransFunc
Plot the transfer function as a function of wavelength: amdlibPlotTransFuncWlen
Plot the transfer function as a function of time: amdlibPlotTransFuncTime. Do not hesitate to read the help to set the wavelength range on which the transfer function is computed.
Calibration of ONE science star file with ONE calibrator star file: amdlibDivideOiData
Calibration of SEVERAL science star files with a FULL-FEATURED transfer function on calibrator stars: amdlibCalibrateOiData, do not hesitate to play with the polDeg= option

Once you have reduced all your data, you can combine them all into a single OI FITS file in order to use it in model-fitting tools (e.g. LITpro) or image-reconstruction tools (e.g. MIRA).

To do that you can use the oifits utility from IAU oifitslib: just type oifits-merge -h in a command line to know how it works
