Next: Writing FITS Up: Conversion between FITS Previous: File naming . The INTAPE -command is used to convert FITS (or IHAP) files to the internal MIDAS format: INTAPE file_list id device [flag] . where file_list is a list of absolute position numbers of files (if input is from tape) to be read with 1 being the first file ( e.g. 1, 3, 5, 50-60 would read from the 1st, 3rd, 5th file plus files 50 through 60 included), and id is an identification prefix of the names of the files created. ...

To: file From: Jon Hagen Date: 12-22-00 Subject: Azimuth (or other axis) Encoder calibration When an encoder assembly (pinion gear, arbor, flex coupling, and encoder) has been removed and repaired, the encoder position must be recalibrated (reset to its standard position). The most obvious procedure is as follows: Procedure I Move the azimuth arm to a known "cal" position, identified by a pair of scribe marks or other prearranged hardware pointers. Suppose the cal position is 360.000 degrees. ...

Kermit writes data as FITS files which are fairly standard but nonetheless there are a few details you may want to be aware of. Kermit FITS files contain an NxNxM array of 32 bit integers. ... The values stored in the 32 bit integers are the sum total of counts read at that pixel during the exposure. ... To achieve this normalization, you almost certainly want to normalize the image by dividing it by the NREADS FITS keyword value. ... The current focus position is stored as the FOCUS keyword. ...

... All the optical elements are mounted in a cryostat aimed at keeping components at a temperature of about 80 K. The focal plane masks (field stops or slits) are mounted on a wheel. ... The collimator is an achromatic doublet lens, which images the entrance pupil of the TNG and provides an almost parallel beam (F-number about 2000) at the pupil plane, where Lyot stops can be placed. Right after the pupil plane, two close wheels mount filters and grisms. ...
