This document describes procedures and suggestions for submission, implementation, and scheduling of calibration programs. It is Presto's goal to implement, schedule, and execute calibration programs as correctly and efficiently as possible. ... Calibration programs added after the Director's Office Review must be submitted to the TTRB at least 8 weeks prior to execution; . All changes to calibration programs must be submitted at least 6 weeks prior to execution; . ...

... hb ( uvd _real , v2 _real ) Function. Return diameter of star for given -distance and squared visibility. Uses calibration implemented in polynomial expressions. caldiameter ( starid _char , calid _char ) Function. Return the diameter of a star using the calibrator and the uncalibrated estimated squared visibilities. npoirates , starid , predictedrate Propagate the stellar flux through the atmosphere and NPOI, and return the predicted count rate for every NPOI channel. ...

... The choice of the spectrograph design (Fig.2) is determined by the quantity R, the overall dimensions of the PF cage and the restrictions on the rigidity of the structure of the device. ... As the camera's objective a fast 4-lens aplanat is used having a focal distance F cam =140 mm and a relative aperture of 1:1.8, the resolution at the centre is no less than 80 gr/mm, that over the field at a distance of 3 mm from the edge along the frame ( ) diagonal is 35 gr/mm. ...

The main steps in the reduction of NIR spectroscopic data are flat-field correction, subtraction of sky emission, wavelength calibration, correction for telluric absorption and correction for optical system plus detector efficency. ... Sky subtracted frames are corrected computing analitically the tilt angle from the instrumental calibration parameters or directly measuring it from the data. ... The same procedures are applied to the reference stars frames to obtain the calibration spectra. ...
