Cannot find the "TellFits_Lick_3100_11100_R10000.fits"

Describe the bug
Hi, for anyone who can help, I tried to install the DBSP_DRP, following the instructions, I should first download the TellFits_Lick_3100_11100_R10000.fits file from https://drive.google.com/drive/folders/1FFRWjUZ58HiDuDD33MYqBzMWDQanBRRy

However, I cannot find this file in the google drive.

Thanks in advance to anyone who can answer me.

Try using TelFit_Palomar_5500_10500_R15000.fits instead (you can change the fileId to 1fPwHi1ZdB3CSqOPH4lDv54TUKkLwFTJb in the download_tellfile bash script).

"5500-10500" in the filename likely represents the wavelength range covered by the file.
How can we process data below 5500 Å using DBSP_DSP?
This file's wavelength range does not seem to fully cover our observed wavelength range (the blue channel is 3228-4774 Å, and the red channel is 6171-7831 Å).

Hello! The TelFit file contains a grid of model atmospheric spectra used for telluric correction. DBSP_DRP will flux the blue and red channels using sensitivity functions created from standards you observe, and account for atmospheric extinction when doing so, but only the red channel can receive a telluric correction. If your red channel goes below 5500 Å, the data below 5500 Å will be ignored when fitting the spectrum for telluric absorption, but I don't recall running into this situation before.
